P2LED1
IPU/O
2
LED indicator for Port 2.
This pin has to be pulled down by 1K resistor in the design for KSZ8864RMN.
50
P2LED0
IPU/O
2
LED indicator for Port 2.
Strap option: Switch MAC3 used only.
PU (default) = Select MII interface for the Switch MAC3 SW3-MII.
PD = Select RMII interface for the Switch MAC3 SW3-RMII.
51
P1LED1
IPU/O
1
LED indicator for Port 1.
Strap option: Switch RMII used only.
PU (default) = Select the device as clock mode. When use RMII interface, all
clock source come from Pin x1/x2 crystal 25MHz.
PD = Select the device as normal mode when use RMII interface. All clock
sources come from SW4-RMII SM4TXC pin with an external input 50MHz clock.
In the normal mode, the 25MHz crystal clock from pin X1/X2 doesn’t take affect
and should disable SW4-RMII SW4RXC 50MHz clock output by the register 87.
The normal mode is used when SW4-RMII receive an external 50MHz RMII
reference clock from pin SM4TXC.
52
P1LED0
IPU/O
1
LED indicator for Port 1.
Strap option: for Switch MAC4 only.
PU (default) = Select MII interface for the Switch MAC4 SW4-MII.
PD = Select RMII interface for the Switch MAC4 SW4-RMII.
