6.2 Signal Descriptions

Table 6-1 describes the signals. The GPIO function (shown in Italics) is the default at reset. The peripheral signals that are listed under them are alternate functions. Some peripheral functions may not be available in all devices. See Table 5-1 for details. Inputs are not 5-V tolerant. All XINTF pins have a drive strength of 4 mA (typical). All GPIO pins are I/O/Z, 4-mA drive typical and have an internal pullup, which can be selectively enabled or disabled on a per-pin basis. This feature only applies to the GPIO pins. The pullups on GPIO0–GPIO11 and GPIO58–GPIO63 pins are not enabled at reset. The pullups on GPIO12–GPIO57 and GPIO64–GPIO87 are enabled upon reset.

BALL #		ZFE
BALL #		DESCRIPTION
JTAG
TRSTM7R8JTAG 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: TRST is an active high test pin and must be maintained low at all times during normal device operation. An external pulldown resistor is recommended 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. (I, ↓)
TCKP9T11JTAG test clock. An external pullup resistor is required on this pin. A 2.2-kΩ resistor generally offers adequate protection.(I)
TMSM8P9JTAG test-mode select (TMS) with internal pullup. This serial control input is clocked into the TAP controller on the rising edge of TCK. (I, ↑)
TDIL6T8JTAG test data input (TDI) with internal pullup. TDI is clocked into the selected register (instruction or data) on a rising edge of TCK. (I, ↑)
TDON7P8JTAG 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.
EMU0N9P10Emulator pin 0. When TRST is driven high, this pin is used as an interrupt to or from the emulator 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.
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. Because this is application-specific, TI recommends validating each each target board for proper operation of the debugger and the application.
EMU1L9R10Emulator pin 1. When TRST is driven high, this pin is used as an interrupt to or from the emulator 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.
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. Because this is application-specific, TI recommends validating each target board for proper operation of the debugger and the application.
Clock
XCLKOUTB14D16Output clock derived from SYSCLKOUT. XCLKOUT is either the same frequency, one-half the frequency, one-fourth the frequency, or one-eighth the frequency of SYSCLKOUT. This is controlled by bit 19 (BY4CLKMODE), bits 18:16 (XTIMCLK), and bit 2 (CLKMODE) in the XINTCNF2 register. At reset, XCLKOUT = SYSCLKOUT/8. The XCLKOUT signal can be turned off by setting XINTCNF2[CLKOFF] to 1. Unlike other GPIO pins, the XCLKOUT pin is not placed in high-impedance state during a reset.
XCLKIND9A12External 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 VSSK. 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 VSS. (I)
X1C8A7Internal/External Oscillator Input. To use the internal oscillator, a quartz crystal 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 VSS. If a 3.3-V external oscillator is used with the XCLKIN pin, X1 must be tied to VSSK. (I)
X2A8A9Internal Oscillator Output. A quartz crystal may be connected across X1 and X2. If X2 is not used it must be left unconnected. (O)
Reset
XRSP8T10Device 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 MCU 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. It is recommended that this pin be driven by an open-drain device.
XRSION8T9XRS I/O Control (I) -  This pin must be connected to the XRS pin on the target board. When XRS is low (reset), the level detected on this pin puts all output buffers on the device in high-impedance mode.

GPIO14H5J3General-purpose input/output 14 (I/O/Z)
TZ3/ XHOLDTrip Zone input 3/External Hold Request. XHOLD, when active (low), requests the external interface (XINTF) to release the external bus and place all buses and strobes into a high-impedance state. To prevent this from happening when TZ3 signal goes active, disable this function by writing XINTCNF2[HOLD] = 1. If this is not done, the XINTF bus will go into high impedance anytime TZ3 goes low. On the ePWM side, TZn signals are ignored by default, unless they are enabled by the code. The XINTF will release the bus when any current access is complete and there are no pending accesses on the XINTF. (I)

TZ4/ XHOLDA Trip Zone input 4/External Hold Acknowledge. The pin function for this option is based on the direction chosen in the GPADIR register. If the pin is configured as an input, then TZ4 function is chosen. If the pin is configured as an output, then XHOLDA function is chosen. XHOLDA is driven active (low) when the XINTF has granted an XHOLD request. All XINTF buses and strobe signals will be in a high-impedance state. XHOLDA is released when the XHOLD signal is released. External devices should only drive the external bus when XHOLDA is active (low). (I/O)
