Description

DBG_​PMODE

O

ITP Power Mode Indicator. This signal is used to transmit processor and power/reset information to the Debugger.

PRDY# O Probe Mode Ready: PRDY# is a processor output used by debug tools to determine processor debug readiness
PREQ# IOD Probe Mode Request: PREQ# is used by debug tools to request debug operation of the processor.
SOC JTAG Signals
SOC_​JTAG_​TCK I/O Test Clock Input (TCK): The test clock input provides the clock for the JTAG test logic.
SOC_​JTAG_​TMS IOD

Test Mode Select (TMS): The signal is decoded by the Test Access Port (TAP) controller

to control test operations.

SOC_​JTAG_​TDI IOD

Test Data Input (TDI): Serial test instructions and data are received by the test logic at

TDI.

SOC_​JTAG_​TDO IOD

Test Data Output (TDO): TDO is the serial output for test instructions and data from the

test logic defined in this standard.

SOC_​JTAG_​TRST# I/O

Test Reset(TRST): Resets the Test Access Port (TAP) logic. This signal should be driven

low during power on Reset.

Breakpoint and Performance Monitor Signals
BPM[0] I/O Breakpoint and Performance Monitor Signals(BPM): Outputs from the processor that indicate the status of breakpoints and programmable counters used for monitoring processor performance.
BPM[1] I/O Breakpoint and Performance Monitor Signals(BPM): Outputs from the processor that indicate the status of breakpoints and programmable counters used for monitoring processor performance.
Boot Halt Signal
BOOTHALT# IOD Boot Halt : This signal is used for platform boot halt.
