ITP and JTAG Pins
Table 10
provides descriptions of the ITP and JTAG signals, which the system manufacturer can
use to implement a JTAG chain and an ITP port if desired.
NOTE:
FS_RESET# and FS_PRDY# are pulled up to VTT inside the mobile processor core.

VTT
JTAG Test Data In:
A serial input port. TAP instructions and data are
shifted into the processor from this port.

VTT
JTAG Test Mode Select:
This pin controls the TAP controller change
sequence.
TCLK

VTT
JTAG Test Clock:
A testability clock for clocking the JTAG boundary
scan sequence.
TRST#

VTT
JTAG Test Reset:
This signal asynchronously resets the TAP
controller in the processor.
FS_PREQ#
I
VTT
Debug Mode Request:
This signal is driven by the ITP and makes a
request to enter debug mode.
FS_PRDY#
O
VTT
Debug Mode Ready:
This signal is driven by the processor and
informs the ITP that the processor is in debug mode.
FS_RESET#
O
VTT
Processor Reset:
The
processor reset status to the ITP.

VTT
GTL+ Termination Voltage:
This pin is used by the POWERON pin
on the ITP debug port to determine when the target system is on. The
POWERON pin is pulled up using a 1-K
resistor to VTT. Other ITP
signals might use this power rail for pullup.
