Register Name:			LI.RMPSCH
Register Description:			Receive Maximum Packet Size Control High Register
Register Address:			103h
Bit #	7	6	5		4	3	2		1	0
Name	RMX15	RMX14		RMX13	RMX12	RMX11	RMX10		RMX9	RMX8
Default	0	0		0	0	0	1		1	1

Bits 7 to 0: Receive Maximum Packet Size (RMX15 to RMX8). These 16 bits indicate the maximum allowable

packet size in bytes. The size includes the FCS bytes, but excludes bit/byte stuffing. Note: If the maximum packet size is less than the minimum packet size, all packets are discarded. When packet processing is disabled, these 16 bits indicate the "packet" size the incoming data is to be broken into.

The maximum packet size allowable is 2016 bytes plus the FCS bytes. Any values programmed that are greater than 2016 + FCS will have the same effect as 2016+ FCS value.

In X.86 mode, the X.86 encapsulation bytes are included in maximum size control.

Bit 2: Receive FCS Errored Packet Count (REPC). This read-only bit indicates that the receive FCS errored packet count is non-zero.

Bit 1: Receive Aborted Packet Count (RAPC). This read-only bit indicates that the receive aborted packet count is non-zero.

Bit 0: Receive Size Violation Packet Count (RSPC). This read-only bit indicates that the receive size violation packet count is non-zero.
