Description
TCK
It
TTL
Test Clock. This signal is used during boundary scan testing to
clock serial data.
TDI

20pF
Test Output. This tristateable signal contains serial data that is
shifted out on the falling edge of TCK.
TMS
Itpu
TTL
Test Mode Select. This signal controls the operation of the TAP
controller. This pin has an internal pull up.
TRST#
Itpu
TTL
Test Reset. A high to low signal forces the TAP controller into a
logic reset state. Must be held low during normal (non-test)
operation. This pin has an internal pullup.
