GPIO 2 connected to ATTINY hardware reset chip (schematic pp 6)

GPIO2, 3 Designated as EJTAG_TDO, EJTAG_TMS

GPIO2, 3 connected to WAKE_L_0, WAKE_L_1 line on PCIe connectors. (schematic pp15)

Is there a conflict on GPIO 2??

GPIOs 2 and 3 are working correctly with updated firmware.

Phase 1 testing of ATTINY hardware reset can be undertaken if required.
