TCK
Input D13 The test clock (TCK) signal provides timing for test
operations that are carried out using the IEEE
P1149.1 test access port. TCK has an integral pull-up
resistor.
TMS
Input B13 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 A13 The test data input (TDI) signal carries test data into
the S/UNI-VORTEX 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 C12 The test data output (TDO) signal carries test data out
of the S/UNI-VORTEX 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
BIAS
Input C13 The active-low test reset (TRSTB) signal provides an
asynchronous S/UNI-VORTEX 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.
Power and Ground
Power E20 When tied to +5V, the BIAS inputs are used to bias
W20 the wells in the input and I/O pads so that the pads
can tolerate 5V on their inputs without forward biasing
internal ESD protection devices. When tied to +3.3V,
the inputs and bi-directional inputs will only tolerate
3.3V level inputs.
