JTAG Test Access Port (TAP) Signals
Pin Name Type Pin
No.
Function
TCK Input B8 The test clock (TCK) signal provides timing for test
operations that are carried out using the IEEE
P1149.1 test access port.
TMS Input
pull-up
B9 The test mode select (TMS) signal controls the test
operations that are carried out using the IEEE
P1149.1 test access port. TMS is sampled on the
rising edge of TCK. TMS has an integral pull-up
resistor.
TDI Input
pull-up
D10 The test data input (TDI) signal carries test data into
the S/UNI-QUAD via the IEEE P1149.1 test access
port. TDI is sampled on the rising edge of TCK. TDI
has an integral pull-up resistor.
TDO Tristate A9 The test data output (TDO) signal carries test data
out of the S/UNI-QUAD via the IEEE P1149.1 test
access port. TDO is updated on the falling edge of
TCK. TDO is a tristate output which is inactive
except when scanning of data is in progress.
TRSTB Input
pull-up
C9 The active-low test reset (TRSTB) signal provides
an asynchronous S/UNI-QUAD test access port
reset via the IEEE P1149.1 test access port.
TRSTB is a Schmitt triggered input with an integral
pull-up resistor.
Note that when not being used, TRSTB must be
connected to the RSTB input.
