1.
The JTAG specification, IEEE 1149.1, recommends that both JTAG_TMS and EJTAG_TMS should be held at 1 while the signal applied at JTAG_TRST_N changes from 0 to 1.
Otherwise, a race may occur if JTAG_TRST_N is deasserted (going from low to high) on a rising edge of JTAG_TCK when either JTAG_TMS or EJTAG_TMS is low, because the
TAP controller might go to either the Run-Test/Idle state or stay in the Test-Logic-Reset state.
