V1P0A
JTAG Test Clock for the JTAG
controller.
TRST_B

V1P0A
JTAG Reset. Resets the JTAG
controller when asserted. The
signal has an internal pull-up
resistor to comply with
1149.1. An external 51-Ω 1%
pull-down resistor is required
to disable JTAG and keep TAP
in safe mode.

JTAG Test Mode Select.
Selects the state of the JTAG
controller. Sampled with the
rising edge of JTCK.

V1P0S
Probe Mode Ready: CPU
response to XXPREQ_B
assertion. Indicates CPU is in
probe mode. Input unused.

2K, PU
V1P0S
Probe Mode Request:
Assertion is a request for the
CPU to enter probe mode. The
CPU responds with XXPRDY_B
assertion once it has entered.
The XXPREQ_B can be
enabled to cause the CPU to
break from C6. External 56 Ω
resistor to Vccp.
