GPIO signals must meet the setup and hold times if they are synchronous or the mnimumpulse width if
they are asynchronous.

1.
The JTAG specification, IEEE 1149.1, recommends that JTAG_TMS should be held at 1 while the signal applied at JTAG_TRST_N
changes from0 to 1. Otherwise, a race may occur if JTAG_TRST_N is deasserted (going fromlow to high) on a rising edge of JTAG_TCK
when JTAG_TMS is low, because the TAP controller mght go to either the Run-Test/Idle state or stay in the Test-Logic-Reset state.
