Pin Function
MAC4 Switch MII receive bit 3.
Strap option:
PD (default) = Disable Switch MII/RMII full-duplex flow control;
PU = Enable Switch MII/RMII full-duplex flow control.
MAC4 Switch MII receive bit 2.
Strap option:
PD (default) = Switch MII/RMII in full-duplex mode;
PU = Switch MII/RMII in half-duplex mode.
MAC4 Switch MII/RMII receive bit 1.
Strap option:
PD (default) =MAC4 Switch SW4-MII/RMII in 100Mbps mode;
PU = MAC4 Switch SW-5MII/RMII in 10Mbps mode.
MAC4 Switch MII/RMII receive bit 0.
Strap option: LED mode
PD (default) = mode 0;
PU = Mode 1.

MAC4 Switch MII collision detect:
Input: SW4-MII MAC modes.
Output: SW4-MII PHY modes.
MAC4 Switch MII modes carrier sense:
Input: SW4-MII MAC modes.
Output: SW4-MII PHY modes.
MAC4 Switch SW4-MII enabled with PHY mode or MAC mode,
have to configure SCONF1 Pin 47 with SCONF0 Pin 48
together.

Port 4 Switch SW4-MII enabled with PHY mode or MAC mode,
have to configure SCONF0 pin 48 with SCONF1 Pin 47
together.
See Pin 47 description.
LED indicator for Port 2.
This pin has to be pulled down by 1K resistor in the design for
KSZ8864RMN.
