JTAG | |||
TRST | 84 | A6 | JTAG test reset with internal pulldown. 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: Do not use pullup resistors on TRST; it has an internal pull-down device. 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. Since this is application-specific, it is recommended that each target board be validated for proper operation of the debugger and the application. (I, ↓) |
TCK | 75 | A10 | JTAG test clock with internal pullup (I, ↑) |
TMS | 74 | B10 | JTAG test-mode select (TMS) with internal pullup. This serial control input is clocked into the TAP controller on the rising edge of TCK. (I, ↑) |
TDI | 73 | C9 | JTAG test data input (TDI) with internal pullup. TDI is clocked into the selected register (instruction or data) on a rising edge of TCK. (I, ↑) |
TDO | 76 | B9 | 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. (O/Z 8 mA drive) |
EMU0 | 80 | A8 | Emulator pin 0. When TRST is driven high, this pin is used as an interrupt to or from the JTAG debug probe system and is defined as input/output through the JTAG scan. This pin is also used to put the device into boundary-scan mode. With the EMU0 pin at a logic-high state and the EMU1 pin at a logic-low state, a rising edge on the TRST pin would latch the device into boundary-scan mode. (I/O/Z, 8 mA drive ↑)
NOTE: An external pullup resistor is recommended on this pin. The value of this resistor should be based on the drive strength of the debugger pods applicable to the design. A 2.2-kΩ to 4.7-kΩ resistor is generally adequate. Since this is application-specific, it is recommended that each target board be validated for proper operation of the debugger and the application. |
EMU1 | 81 | B7 | Emulator pin 1. When TRST is driven high, this pin is used as an interrupt to or from the JTAG debug probe system and is defined as input/output through the JTAG scan. This pin is also used to put the device into boundary-scan mode. With the EMU0 pin at a logic-high state and the EMU1 pin at a logic-low state, a rising edge on the TRST pin would latch the device into boundary-scan mode. (I/O/Z, 8 mA drive ↑)
NOTE: An external pullup resistor is recommended on this pin. The value of this resistor should be based on the drive strength of the debugger pods applicable to the design. A 2.2-kΩ to 4.7-kΩ resistor is generally adequate. Since this is application-specific, it is recommended that each target board be validated for proper operation of the debugger and the application. |
FLASH | |||
VDD3VFL | 96 | C4 | 3.3-V Flash Core Power Pin. This pin should be connected to 3.3 V at all times. On the ROM parts (C280x), this pin should be connected to VDDIO. |
TEST1 | 97 | A3 | Test Pin. Reserved for TI. Must be left unconnected. (I/O) |
TEST2 | 98 | B3 | Test Pin. Reserved for TI. Must be left unconnected. (I/O) |
CLOCK | |||
XCLKOUT | 66 | E8 | 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 the 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. Unlike other GPIO pins, the XCLKOUT pin is not placed in high-impedance state during a reset. (O/Z, 8 mA drive). |
XCLKIN | 90 | B5 | External Oscillator Input. This pin is to feed a clock from an external 3.3-V oscillator. In this case, the X1 pin must be tied to GND. If a crystal/resonator is used (or if an external 1.8-V oscillator is used to feed clock to X1 pin), this pin must be tied to GND. (I) |
X1 | 88 | E6 | Internal/External Oscillator Input. To use the internal oscillator, a quartz crystal or a ceramic resonator may be connected across X1 and X2. The X1 pin is referenced to the 1.8-V core digital power supply. A 1.8-V external oscillator may be connected to the X1 pin. In this case, the XCLKIN pin must be connected to ground. If a 3.3-V external oscillator is used with the XCLKIN pin, X1 must be tied to GND. (I) |
X2 | 86 | C6 | Internal Oscillator Output. A quartz crystal or a ceramic resonator may be connected across X1 and X2. If X2 is not used it must be left unconnected. (O) |
RESET | |||
XRS | 78 | B8 | Device Reset (in) and Watchdog Reset (out).
Device reset. XRS causes the device to terminate execution. The PC will point to the address contained at the location 0x3FFFC0. When XRS is brought to a high level, execution begins at the location pointed to by the PC. This pin is driven low by the DSP when a watchdog reset occurs. During watchdog reset, the XRS pin is driven low for the watchdog reset duration of 512 OSCCLK cycles. (I/OD, ↑) The output buffer of this pin is an open-drain with an internal pullup. If this pin is driven by an external device, it should be done using an open-drain device. |
