Output data for the IEEE 1149.1 JTAG interface.
Used to reset the IEEE 1149.1 JTAG interface.
Important:
The JTG_TRST_N signal must be asserted (driven low) during power-up, otherwise the TAP controller
will not be initialized properly and the processor may be locked.
When the JTAG interface is not being used, the signal must be pulled low using a 10-KΩ resistor.
Used as the clock for the IEEE 1149.1 JTAG interface.

Used for test purposes only.
Must be pulled high using a 10-KΩ resistor for normal operation.
Used as a reset input to the device when PWRON_RESET_N is in an inactive state and once
power up conditions are met. Power up conditions include the following:
Signal used at power up to reset all internal logic to a known state after the PLL has achieved a
locked state. The PWRON_RESET_N signal is a 3.3-V signal.
Used for test purposes only.
Must be pulled high using a 10-KΩ resistor for normal operation.
