I have a simple doubt about resetting sequence of Tap state machine One way of resetting TAP FSM is through trst signal. Making trst
1(along with TMS=1 for the time trst transitions from 0 to 1) resets the state machine and it enter run-test-idle mode.A other way is by asserting TMS=1 for five TCK.. But am not able to do it this way.. Any clues where i may be going wrong? What should be the value on other test signals at this time? Since in my case the TAP remains in test-logic-reset state
