6.2.1 Signal Descriptions

PIN NAMEPIN NO.I/O/Z(1)DESCRIPTION
PZ
PZP		PN
PFP
JTAG
TRST1210IJTAG test reset with internal pulldown (PD). TRST, when driven high, gives the scan system control of the operations of the device. If this signal is not connected or driven low, the device operates in its functional mode, and the test reset signals are ignored.
NOTE:TRST is an active-high test pin and must be maintained low at all times during normal device operation. An external pulldown resistor is required on this pin. The value of this resistor should be based on drive strength of the debugger pods applicable to the design. A 2.2-kΩ resistor generally offers adequate protection. Because this is application-specific, TI recommends validating each target board for proper operation of the debugger and the application. (↓)
TCKSee GPIO38ISee GPIO38. JTAG test clock with internal pullup. (↑)
TMSSee GPIO36ISee GPIO36. JTAG test-mode select (TMS) with internal pullup. This serial control input is clocked into the TAP controller on the rising edge of TCK. (↑)
TDISee GPIO35ISee GPIO35. JTAG test data input (TDI) with internal pullup. TDI is clocked into the selected register (instruction or data) on a rising edge of TCK. (↑)
TDOSee GPIO37O/ZSee GPIO37. JTAG scan out, test data output (TDO). The contents of the selected register (instruction or data) are shifted out of TDO on the falling edge of TCK.
(8-mA drive)
FLASH
VDD3VFL46373.3-V Flash Core Power Pin. This pin should be connected to 3.3 V at all times.
TEST24536I/OTest Pin. Reserved for TI. Must be left unconnected.
CLOCK
XCLKOUTSee GPIO18O/ZSee GPIO18. Output clock derived from SYSCLKOUT. XCLKOUT is either the same frequency, one-half the frequency, or one-fourth the frequency of SYSCLKOUT. This is controlled by bits 1:0 (XCLKOUTDIV) in the XCLK register. At reset, XCLKOUT = SYSCLKOUT/4. The XCLKOUT signal can be turned off by setting XCLKOUTDIV to 3. The mux control for GPIO18 must also be set to XCLKOUT for this signal to propogate to the pin.
XCLKINSee GPIO19 and GPIO38ISee GPIO19 and GPIO38. External oscillator input. Pin source for the clock is controlled by the XCLKINSEL bit in the XCLK register, GPIO38 is the default selection. This pin feeds a clock from an external 3.3-V oscillator. In this case, the X1 pin, if available, must be tied to GND and the on-chip crystal oscillator must be disabled through bit 14 in the CLKCTL register. If a crystal or resonator is used, the XCLKIN path must be disabled by bit 13 in the CLKCTL register.
NOTE: Designs that use the GPIO38/XCLKIN/TCK pin to supply an external clock for normal device operation may need to incorporate some hooks to disable this path during debug using the JTAG connector. This is to prevent contention with the TCK signal, which is active during JTAG debug sessions. The zero-pin internal oscillators may be used during this time to clock the device.
X16048IOn-chip 1.8-V crystal-oscillator input. To use this oscillator, a quartz crystal or a ceramic resonator must be connected across X1 and X2. In this case, the XCLKIN path must be disabled by bit 13 in the CLKCTL register. If this pin is not used, it must be tied to GND.
X25947OOn-chip crystal-oscillator output. A quartz crystal or a ceramic resonator must be connected across X1 and X2. If X2 is not used, it must be left unconnected.
RESET
XRS119I/ODDevice Reset (in) and Watchdog Reset (out). These devices have a built-in power-on reset (POR) and brownout reset (BOR) circuitry. During a power-on or brownout condition, this pin is driven low by the device. An external circuit may also drive this pin to assert a device reset. This pin is also driven low by the MCU when a watchdog reset occurs. During watchdog reset, the XRS pin is driven low for the watchdog reset duration of 512 OSCCLK cycles. A resistor with a value from 2.2 kΩ to 10 kΩ should be placed between XRS and VDDIO. If a capacitor is placed between XRS and VSS for noise filtering, it should be 100 nF or smaller. These values will allow the watchdog to properly drive the XRS pin to VOL within 512 OSCCLK cycles when the watchdog reset is asserted. Regardless of the source, a device reset causes the device to terminate execution. The program counter points to the address contained at the location 0x3F FFC0. When reset is deactivated, execution begins at the location designated by the program counter. The output buffer of this pin is an open-drain device with an internal pullup. (↑) If this pin is driven by an external device, it should be done using an open-drain device.

SCITXDBOSCI-B transmit data
XCLKOUTO/ZOutput clock derived from SYSCLKOUT. XCLKOUT is either the same frequency, one-half the frequency, or one-fourth the frequency of SYSCLKOUT. This is controlled by bits 1:0 (XCLKOUTDIV) in the XCLK register. At reset, XCLKOUT = SYSCLKOUT/4. The XCLKOUT signal can be turned off by setting XCLKOUTDIV to 3. The mux control for GPIO18 must also be set to XCLKOUT for this signal to propogate to the pin.
GPIO196452I/O/ZGeneral-purpose input/output 19
XCLKINIExternal Oscillator Input. The path from this pin to the clock block is not gated by the mux function of this pin. Care must be taken not to enable this path for clocking if it is being used for the other peripheral functions.

(1) I = Input, O = Output, Z = High Impedance, OD = Open Drain, ↑ = Pullup, ↓ = Pulldown
(2) The GPIO function (shown in bold italics) is the default at reset. The peripheral signals that are listed under them are alternate functions. For JTAG pins that have the GPIO functionality multiplexed, the input path to the GPIO block is always valid. The output path from the GPIO block and the path to the JTAG block from a pin is enabled or disabled based on the condition of the TRST signal. See the Systems Control and Interrupts chapter of the TMS320x2806x Technical Reference Manual .
(3) Depending on your USB application, additional pins may be required to maintain compliance with the USB 2.0 Specification. For more information, see the Universal Serial Bus (USB) Controller chapter of the TMS320x2806x Technical Reference Manual .
