Port
MQ/FMQ: Port 5 Switch MII receive clock,
Input: SW5-MII MAC mode, Output: SW5-MII PHY mode.
RQ: Output SW5-RMII 50MHz clock, this clock is used when
opposite doesn’t provide RMII reference clock or the system
doesn’t provide an external 50MHz clock for the RMII interface.
MQ/FMQ: SMRXDV is for Switch MAC5 MII receive data valid.
RQ: SMCRSDV is for MAC5 RMII Carrier Sense/Receive Data
Valid Output.
MQ/FMQ: Port 5 Switch MII receive bit 3.
RQ: no connection for RMII
Strap option:
PD (default) = Disable Switch SW5-MII full-duplex flow control
PU = Enable Switch SW5-MII full-duplex flow control.
MQ/FMQ: Port 5 Switch MII receive bit 2.
RQ: no connection for RMII
Strap option:
PD (default) = Switch SW5-MII in full-duplex mode;
PU = Switch SW5-MII in half-duplex mode.
Port 5 Switch MII/RMII receive bit 1.
Strap option:
Port 5 Switch MII/RMII receive bit 0.
Strap option:
LED mode
PD (default) = mode 0; PU = mode 1. See “Register 11.”
Mode 0, link at:
100/Full LEDx[2,1,0] = 0, 0, 0
100/Half LEDx[2,1,0] = 0, 1, 0
10/Full LEDx[2,1,0] = 0, 0, 1
10/Half LEDx[2,1,0] = 0, 1, 1
Mode 1, link at:
100/Full LEDx[2,1,0] = 0, 1, 0
100/Half LEDx[2,1,0] = 0, 1, 1
10/Full LEDx[2,1,0] = 1, 0, 0
10/Half LEDx[2,1,0] = 1, 0, 1
