MII Receive Error.
Active high signal to indicate that there is error condition
detected by ADM7001. When error is detected, RXER will
be high and maintains high until RXDV is de-asserted.
RMII Receive Error.
Active high signal to indicate that there is error condition
detected by ADM7001. When error is detected, RXER will
be high and maintains high until CRSDV is de-asserted.
No Operation in GPSI Mode.
GPSI Mode Select
Value on this pin will be sampled by ADM7001 during
power on reset to form GPSI internal control signal.
Together with RMII_EN, these two pins form three possible
internal supported by ADM7001.
