TCK — TEST CLOCK (INPUT)
edge of TCK and all outputs propagate from the falling edge
of TCK.
TMS — TEST MODE SELECT (INPUT)
is the command input for the TAP controller state machine.
An undriven TMS input will produce the same result as a
logic 1 input level.
TDI — TEST DATA IN (INPUT)
the input side of the serial registers placed between TDI and
TDO. The register placed between TDI and TDO is deter-
mined by the state of the TAP controller state machine and
Clocks all TAP events. All inputs are captured on the rising
The TMS input is sampled on the rising edge of TCK. This
The TDI input is sampled on the rising edge of TCK. This is

NOTE: The value adjacent to each state transition represents the signal present at TMS at the rising edge of TCK.

the instruction that is currently loaded in the TAP instruction
register (see Figure 5). An undriven TDI pin will produce the
same result as a logic 1 input level.
TDO — TEST DATA OUT (OUTPUT)
state machine (see Figure 5). Output changes in response to
the falling edge of TCK. This is the output side of the serial
registers placed between TDI and TDO.
TRST — TAP RESET
1149.1. Asserting the asynchronous TRST places the TAP
controller in test–logic reset state. Test–logic reset state can
also be entered by holding TMS high for five rising edges of
TCK. This type of reset does not affect the operation of the
system logic.
