Table 125. RX FIFO Errored Frame Drop Counter Ports 0 - 3 ($0x5A2 - 0x5A5) (Sheet 2 of 2)

Name	Description	Address	Type	Default
	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
RX FIFO Errored	Drop Enable ($0x59F)” and the “RX
Frame Drop Counter	Packet Filter Control ($ Port_Index +	0x5A4	R	0x00000000
on Port 2	0x19)”.
	• Frames are greater than the “Max
	Frame Size (Addr: Port_Index +
	0x0F)”.
	This register is cleared on Read.
	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
RX FIFO Errored	Drop Enable ($0x59F)” and the “RX
Frame Drop Counter	Packet Filter Control ($ Port_Index +	0x5A5	R	0x00000000
on Port 3	0x19)”.
	• Frames are greater than the “Max
	Frame Size (Addr: Port_Index +
	0x0F)”.
	This register is cleared on Read.

Table 126. RX FIFO SPI3 Loopback Enable for Ports 0 - 3 ($0x5B2)

Bit	Name	Description		Type1	Default
Register Description: Enables the TX SPI3 port to send packets into the RX_FIFO instead of					0x00000000
into the TX FIFO, creating a SPI3 loopback.
