Signal Description
TCK
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
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
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.
