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 3.3V tolerant.
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 3.3V tolerant.
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.
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 3.3V tolerant.
