6 Detailed Description

6.1 Overview

The MSP430F6459 is an ultra-low-power microcontroller that consists of several features which include different sets of peripherals targeted for various applications. The architecture, combined with five low-power modes, is optimized to achieve extended battery life in portable measurement applications.

The device features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows the device to wake up from low-power modes to active mode in 3 μs (typical).

6.2 CPU

The MSP430 CPU has a 16-bit RISC architecture that is highly transparent to the application. All operations, other than program-flow instructions, are performed as register operations in conjunction with seven addressing modes for source operand and four addressing modes for destination operand.

The CPU is integrated with 16 registers that provide reduced instruction execution time. The register-to-register operation execution time is one cycle of the CPU clock.

Four of the registers, R0 to R3, are dedicated as program counter, stack pointer, status register, and constant generator, respectively. The remaining registers are general-purpose registers (see Figure 6-1).

Peripherals are connected to the CPU using data, address, and control buses, and can be handled with all instructions.

For further details, see the CPUX Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU391).

6.3 Instruction Set

The instruction set consists of the original 51 instructions with three formats and seven address modes and additional instructions for the expanded address range. Each instruction can operate on word and byte data. Table 6-1 shows examples of the three types of instruction formats; Table 6-2 shows the address modes.

Table 6-1 Instruction Word Formats

INSTRUCTION WORD FORMAT	EXAMPLE	OPERATION
Dual operands, source-destination	ADD R4,R5	R4 + R5 → R5
Single operands, destination only	CALL R8	PC → (TOS), R8 → PC
Relative jump, unconditional or conditional	JNE	Jump-on-equal bit = 0

(Non)maskable: the individual interrupt-enable bit can disable an interrupt event, but the general-interrupt enable cannot disable it.

(4) Reserved interrupt vectors at addresses are not used in this device and can be used for regular program code if necessary. To maintain compatibility with other devices, TI recommends reserving these locations.

(5) Only on devices with peripheral module LCD_B, otherwise reserved.

(6) Only on devices with peripheral module LDO-PWR.

6.7 Bootloader (BSL)

The BSL enables users to program the flash memory or RAM using various serial interfaces. Access to the device memory by the BSL is protected by an user-defined password. For complete description of the features of the BSL and its implementation, see MSP430 Programming WIth the Bootloader (BSL) (SLAU319).

6.7.1 UART BSL

MSP4306459 comes preprogrammed with the UART BSL. Use of the UART BSL requires external access to six pins (see Table 6-5).

6.8 JTAG Operation

6.8.1 JTAG Standard Interface

The MSP430 family supports the standard JTAG interface which requires four signals for sending and receiving data. The JTAG signals are shared with general-purpose I/O. The TEST/SBWTCK pin is used to enable the JTAG signals. In addition to these signals, the RST/NMI/SBWTDIO is required to interface with MSP430 development tools and device programmers. Table 6-6 lists the JTAG pin requirements. For further details on interfacing to development tools and device programmers, see the MSP430 Hardware Tools User's Guide (SLAU278). For a complete description of the features of the BSL and its implementation, see the MSP430 Programming With the Bootloader User's Guide (SLAU319).

6.8.2 Spy-Bi-Wire Interface

In addition to the standard JTAG interface, the MSP430 family supports the two wire Spy-Bi-Wire interface. Spy-Bi-Wire can be used to interface with MSP430 development tools and device programmers. Table 6-7 lists the Spy-Bi-Wire interface pin requirements. For further details on interfacing to development tools and device programmers, see the MSP430 Hardware Tools User's Guide (SLAU278). For a complete description of the features of the JTAG interface and its implementation, see MSP430 Programming Via the JTAG Interface (SLAU320).

6.9 Flash Memory

The flash memory can be programmed through the JTAG port, Spy-Bi-Wire (SBW), the BSL, or in-system by the CPU. The CPU can perform single-byte, single-word, and long-word writes to the flash memory. Features of the flash memory include:

Flash memory has n segments of main memory and four segments of information memory (A to D) of 128 bytes each. Each segment in main memory is 512 bytes in size.
Segments 0 to n may be erased in one step, or each segment may be individually erased.
Segments A to D can be erased individually, or as a group with segments 0 to n. Segments A to D are also called information memory.
Segment A can be locked separately.

For further information, see the Flash Controller Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU392).

6.10 Memory Integrity Detection (MID)

The MID is an add-on to the MSP430 flash memory controller. MID provides additional functionality over the regular flash operation methods. Main purpose of the MID function is gaining higher reliability of flash content and overall system integrity in harsh environments and application areas requiring such features. The on-chip MID ROM contains the factory programmed MID support software. This software package provides several software functions that allow to use all MID features.

The MID functionality can be enabled for different flash memory ranges. These memory ranges are selectable by the cw0 parameter of the MID function MidEnable(). Details about address range coverage is listed in Table 6-8.

For further information, see the MID Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU459).

6.11 RAM

The RAM is made up of n sectors. Each sector can be completely powered down to save leakage; however, all data is lost. Features of the RAM include:

RAM has n sectors. The size of a sector can be found in Section 6.6.
Each sector 0 to n can be complete disabled; however, data retention is lost.
Each sector 0 to n automatically enters low-power retention mode when possible.

For further information, see the RAM Controller Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU393).

6.12 Backup RAM

The backup RAM provides a limited number of bytes of RAM that are retained during LPMx.5 and during operation from a backup supply if the battery backup system module is implemented.

There are 8 bytes of backup RAM available. It can be word-wise accessed by the control registers BAKMEM0, BAKMEM1, BAKMEM2, and BAKMEM3.

For further information, see the Backup RAM Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU394).

6.13 Peripherals

Peripherals are connected to the CPU through data, address, and control buses. Peripherals can be handled using all instructions. For complete module descriptions, see the MSP430x5xx and MSP430x6xx Family User's Guide (SLAU208).

6.13.1 Digital I/O

There are up to nine 8-bit I/O ports implemented: P1 through P9 are complete and port PJ contains four individual I/O ports.

All individual I/O bits are independently programmable.
Any combination of input, output, and interrupt conditions is possible.
Programmable pullup or pulldown on all ports.
Programmable drive strength on all ports.
Edge-selectable interrupt input capability for all the eight bits of ports P1, P2, P3, and P4.
Read and write access to port-control registers is supported by all instructions.
Ports can be accessed byte-wise (P1 through P9) or word-wise in pairs (PA through PD).

For further information, see the Digital I/O Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU396).

6.13.2 Port Mapping Controller

The port mapping controller allows the flexible and reconfigurable mapping of digital functions to port P2. Table 6-9 lists the available mappings, and Table 6-10 lists the default settings.

For further information, see the Port Mapping Controller Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU397).

6.13.3 Oscillator and System Clock

The clock system is supported by the Unified Clock System (UCS) module that includes support for a 32-kHz watch crystal oscillator (in XT1 LF mode; XT1 HF mode is not supported), an internal very-low-power low-frequency oscillator (VLO), an internal trimmed low-frequency oscillator (REFO), an integrated internal digitally controlled oscillator (DCO), and a high-frequency crystal oscillator (XT2). The UCS module is designed to meet the requirements of both low system cost and low power consumption. The UCS module features digital frequency locked loop (FLL) hardware that, in conjunction with a digital modulator, stabilizes the DCO frequency to a programmable multiple of the watch crystal frequency. The internal DCO provides a fast turnon clock source and stabilizes in 3 µs (typical). The UCS module provides the following clock signals:

Auxiliary clock (ACLK), sourced from a 32-kHz watch crystal (XT1), a high-frequency crystal (XT2), the internal low-frequency oscillator (VLO), the trimmed low-frequency oscillator (REFO), or the internal digitally-controlled oscillator DCO.
Main clock (MCLK), the system clock used by the CPU. MCLK can be sourced by same sources available to ACLK.
Sub-Main clock (SMCLK), the subsystem clock used by the peripheral modules. SMCLK can be sourced by same sources available to ACLK.
ACLK/n, the buffered output of ACLK, ACLK/2, ACLK/4, ACLK/8, ACLK/16, ACLK/32.

For further information, see the UCS Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU390).

6.13.4 Power-Management Module (PMM)

The PMM includes an integrated voltage regulator that supplies the core voltage to the device and contains programmable output levels to provide for power optimization. The PMM also includes supply voltage supervisor (SVS) and supply voltage monitoring (SVM) circuitry, as well as brownout protection. The brownout circuit is implemented to provide the proper internal reset signal to the device during power-on and power-off. The SVS and SVM circuitry detects if the supply voltage drops below a user-selectable level and supports both supply voltage supervision (the device is automatically reset) and supply voltage monitoring (the device is not automatically reset). SVS and SVM circuitry is available on the primary supply and core supply.

For further information, see the PMM Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU388).

6.13.5 Hardware Multiplier (MPY)

The multiplication operation is supported by a dedicated peripheral module. The module performs operations with 32-bit, 24-bit, 16-bit, and 8-bit operands. The module supports signed and unsigned multiplication as well as signed and unsigned multiply-and-accumulate operations.

For further information, see the MPY Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU404).

6.13.6 Real-Time Clock (RTC_B)

The RTC_B module can be configured for real-time clock (RTC) or calendar mode providing seconds, minutes, hours, day of week, day of month, month, and year. Calendar mode integrates an internal calendar which compensates for months with less than 31 days and includes leap year correction. The RTC_B also supports flexible alarm functions and offset-calibration hardware. The implementation on this device supports operation in LPM3.5 mode and operation from a backup supply.

The application report Using the MSP430 RTC_B Module With Battery Backup Supply (SLAA665) describes how to use the RTC_B with battery backup supply functionality to retain the time and keep the RTC counting through loss of main power supply, as well as how to handle correct reinitialization when the main power supply is restored.

For further information, see the RTC_B Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU403).

6.13.7 Watchdog Timer (WDT_A)

The primary function of the WDT_A module is to perform a controlled system restart after a software problem occurs. If the selected time interval expires, a system reset is generated. If the watchdog function is not needed in an application, the module can be configured as an interval timer and can generate interrupts at selected time intervals.

For further information, see the WDT_A Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU399).

6.13.8 System Module (SYS)

The SYS module handles many of the system functions within the device. These include power-on reset and power-up clear handling, NMI source selection and management, reset interrupt vector generators (see Table 6-11), bootloader entry mechanisms, and configuration management (device descriptors). SYS also includes a data exchange mechanism using JTAG called a JTAG mailbox that can be used in the application.

For further information, see the SYS Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU387).

6.13.9 DMA Controller

The DMA controller allows movement of data from one memory address to another without CPU intervention. For example, the DMA controller can be used to move data from the ADC12_A conversion memory to RAM. Using the DMA controller can increase the throughput of peripheral modules. The DMA controller reduces system power consumption by allowing the CPU to remain in sleep mode, without having to awaken to move data to or from a peripheral.

For further information, see the DMA Controller Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU395).

6.13.15 Comparator_B

The primary function of the Comparator_B module is to support precision slope analog-to-digital conversions, battery voltage supervision, and monitoring of external analog signals.

For further information, see the COMP_B Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU408).

6.13.16 ADC12_A

The ADC12_A module supports fast 12-bit analog-to-digital conversions. The module implements a 12-bit SAR core, sample select control, reference generator, and a 16 word conversion-and-control buffer. The conversion-and-control buffer allows up to 16 independent ADC samples to be converted and stored without any CPU intervention.

For further information, see the ADC12_A Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU406).

6.13.17 DAC12_A

The DAC12_A module is a 12-bit, R-ladder, voltage output DAC. The DAC12_A may be used in 8-bit or 12-bit mode, and may be used in conjunction with the DMA controller. When multiple DAC12_A modules are present, they may be grouped together for synchronous operation.

6.13.18 CRC16

The CRC16 module produces a signature based on a sequence of entered data values and can be used for data checking purposes. The CRC16 module signature is based on the CRC-CCITT standard.

For further information, see the CRC Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU398).

6.13.19 Voltage Reference (REF) Module

The REF module is responsible for generation of all critical reference voltages that can be used by the various analog peripherals in the device.

For further information, see the REF Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU405).

6.13.20 LCD_B

The LCD_B driver generates the segment and common signals that are required to drive a liquid crystal display (LCD). The LCD_B controller has dedicated data memories to hold segment drive information. Common and segment signals are generated as defined by the mode. Static, 2-mux, 3-mux, and 4-mux LCDs are supported. The module can provide a LCD voltage independent of the supply voltage with its integrated charge pump. It is possible to control the level of the LCD voltage, and thus contrast, by software. The module also provides an automatic blinking capability for individual segments.

The LCD_B module is only available on the MSP430F665x and MSP430F645x devices.

For further information, see the LCD_B Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU409).

6.13.21 LDO and PU Port

The integrated 3.3-V power system incorporates an integrated 3.3-V LDO regulator that allows the entire MSP430 microcontroller to be powered from nominal 5-V LDOI when it is made available for the system. Alternatively, the power system can supply power only to other components within the system, or it can be unused altogether.

The Port U Pins (PU.0 and PU.1) function as general-purpose high-current I/O pins. These pins can only be configured together as either both inputs or both outputs. Port U is supplied by the LDOO rail. If the 3.3-V LDO is not being used in the system (disabled), the LDOO pin can be supplied externally.

The LDO-PWR module (LDO and PU Port) is only available on the MSP430F645x and MSP430F535x devices.

6.13.22 Embedded Emulation Module (EEM) (L Version)

The EEM supports real-time in-system debugging. The L version of the EEM has the following features:

Eight hardware triggers or breakpoints on memory access
Two hardware triggers or breakpoints on CPU register write access
Up to ten hardware triggers can be combined to form complex triggers or breakpoints
Two cycle counters
Sequencer
State storage
Clock control on module level

For further information, see the EEM Module (Chapter Excerpt From MSP430x5xx Family, SLAU208) (SLAU414).
