Signal Description
TCK
Input
Input
Test Clock
—TCK is a test clock input signal used to synchronize the
JTAG test logic. It has an internal pull-up resistor.
This input is 5 V tolerant.
TDI
Input
Input
Test Data Input
—TDI is a test data serial input signal used for test
instructions and data. TDI is sampled on the rising edge of TCK and
has an internal pull-up resistor.
This input is 5 V tolerant.
TDO
Output
Tri-stated
Test Data Output
—TDO is a test data serial output signal used for
test instructions and data. TDO is tri-statable and is actively driven in
the shift-IR and shift-DR controller states. TDO changes on the falling
edge of TCK.
TMS
Input
Input
Test Mode Select
—TMS is an input signal used to sequence the test
controller’s state machine. TMS is sampled on the rising edge of TCK
and has an internal pull-up resistor.
This input is 5 V tolerant.
