PRODUCTION DATA.
Device Identification
Read-only registers in the system control module provide information about the MCU, such as version, part number, pin count, operating temperature range, and available peripherals on the device. The Device Identification 0 (DID0) and Device Identification 1 (DID1) registers provide details about the version, package, and temperature range of the device. The peripheral present registers starting at system control offset 0x300, such as the Watchdog Timer Peripheral Present (PPWD) register, provide information on how many of each type of module are included on the device. Finally, information about the capabilities of the on-chip peripherals are provided at offset 0xFC0 in the register space of each peripheral in the peripheral properties registers, such as the GPTM Peripheral Properties (GPTMPP). In addition, four unique identifier registers, Unique Identifier n (UNIQUEIDn), provide a 128-bit unique identifier that cannot be modified for each device.
JTAG Identification
Figure 6-3 shows the format for the 32-bit IDCODE Data Register defined by the IEEE Standard 1149.1. The major uses of the JTAG port are for manufacturer testing of component assembly and program development and debug. To facilitate the use of auto-configuration debug tools, the IDCODE instruction outputs a value of 0x4BA0.0477. This value lets the debuggers automatically configure themselves to work correctly with the Cortex-M4F during debug.
ROM Version
The internal ROM is at address 0x0100.0000 of the device memory map.
