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.
