RX FIFO Errored
Frame Drop Counter
on Port 2
This register counts all frames dropped from the
RX FIFO for port 2 by meeting one of the
following conditions:
• Frames are removed in conjunction
with the“RX FIFO Errored Frame
Drop Enable ($0x59F)” and the “RX
Packet Filter Control ($ Port_Index +
0x19)”.
• Frames are greater than the “Max
Frame Size (Addr: Port_Index +
0x0F)”.
This register is cleared on Read.

RX FIFO Errored
Frame Drop Counter
on Port 3
This register counts all frames dropped from the
RX FIFO for port 3 by meeting one of the
following conditions:
• Frames are removed in conjunction
with the“RX FIFO Errored Frame
Drop Enable ($0x59F)” and the “RX
Packet Filter Control ($ Port_Index +
0x19)”.
• Frames are greater than the “Max
Frame Size (Addr: Port_Index +
0x0F)”.
This register is cleared on Read.
