IEEE 1149.1 Test Access Port (JTAG)
31.5.2
The TAP controller is a state machine that changes state based on the sequence of logical values on the
TMS pin.
TMS signal sampled on the rising edge of the TCLK signal.
Asserting the TRST signal asynchronously resets the TAP controller to the test-logic-reset state. As
Figure 31-3
causes the state machine to enter the test-logic-reset state, whatever the initial state.
