TMS (Test Mode Select)
Input
Summary
TMS specifies the test function and sequence of test changes
for testing on the Test Access Port (TAP).
Sampled
The processor samples TMS every rising TCK edge. TMS has
an internal pullup resistor.
TMS is always sampled, except while RESET or INIT is
asserted.
Details
If TMS is asserted for five or more clocks, the TAP controller
enters its test-reset-logic state, regardless of the controller
state. This action is the same as that achieved by asserting
TRST.
See the IEEE Standard Test Access Port and Boundary-Scan
Architecture (IEEE 1149.1) specification for a description of
how the TAP signals and instructions are used for testing.
