1.2V digital core V
PHY[5] MII/RMII transmit enable.
MQ/FMQ: PHY[5] MII transmit bit 3.
RQ: no connection for RMII.
MQ/FMQ: PHY[5] MII transmit bit 2.
RQ: no connection for RMII.
PHY[5] MII/RMII transmit bit 1.
PHY[5] MII/RMII transmit bit 0.
MQ/FMQ: PHY[5] MII transmit error. RQ: no connection for RMII.
MQ/FMQ: Output PHY[5] MII transmit clock
RQ: Input PHY[5] RMII reference clock, 50MHz ±50ppm, the
50MHz clock comes from PMRXC Pin 60.
3.3V, 2.5V or 1.8V digital V
MQ/FMQ: Output PHY[5] MII receive clock.
RQ: Output PHY[5] RMII reference clock, this clock is used when
opposite doesn’t provide RMII 50MHz clock or the system doesn’t
provide an external 50MHz clock for the P5-RMII interface.
MQ/FMQ: PMRXDV is for PHY[5] MII receive data valid.
RQ: PMCRSDV is for PHY[5] RMII
Valid Output.
