Pin Function
1 = Normal function.
0 = MC in loopback mode, or MC abnormal conditions occur.
1 = Drop OAM frames and Ethernet frames with the following errors – CRS, undersize,
oversize. Loopback Ethernet frames with only good CRC and valid length.
0 = Drop OAM frames only. Loopback all Ethernet frames including those with errors.
1 = Perform MC loopback at PHY of port 1.
0 = Perform MC loopback at MAC of port 2
Note: An external 1K pull-down is needed on this pin if it is connected to an LED. The
1K resistor will not turn ON the LED.
See description in pin 4.

and 123), and V
connected to 3.3V power rail by a 100ohm resistor for the internal LDO application.
LED display mode select.
See description in pins 1 and 4.
Note: An external 1K pull-down is needed on this pin if it is connected to an LED. The
1K resistor will not turn ON the LED.
See description in pin 1.
Strap pin for RMII Mode
1 = Enable
0 = Disable
After reset, this pin has no meaning and is a no connect.
Hardware pin overwrite
1 = Enable: All strap-in pin configurations are overwritten by the EEPROM
configuration data, except for P2ANEN (pin 13), P2SPD (pin 14), P2DPX (pin 15) and
ML_EN (pin 34). After reset, the pin state for P2ANEN, P2SPD and P2DPX is polled by
the KSZ8893FQL.
0 = Disable: All strap-in pin configurations are overwritten by the EEPROM
configuration data.
Port 2 Auto MDI/MDI-X
PD (default) = enable
PU = disable
Port 2 MDI/MDI-X setting when auto MDI/MDI-X is disabled.
PD (default) = MDI-X (transmit on TXP2 / TXM2 pins)
PU = MDI, (transmit on RXP2 / RXM2 pins)
1 = Enable auto-negotiation on port 1
0 = Disable auto-negotiation on port 1
1 = Force port 1 to 100BT if P1ANEN = 0
0 = Force port 1 to 10BT if P1ANEN = 0
