Bank 48 Port 1 VID Control Register (0x04): P1VIDCR
This register contains the global per port control for the switch function.
Note: This VID Control register serves two purposes:
1. Associated with the ingress untagged packets, and used for egress tagging.
2. Default VID for the ingress untagged or null-VID-tagged packets, and used for address lookup.

Ingress Limit Mode
These bits determine what kinds of frames are limited and counted against Ingress
limiting as follows:
00 = Limit and count all frames.
01 = Limit and count Broadcast, Multicast, and flooded unicast frames.
10 = Limit and count Broadcast and Multicast frames only.
11 = Limit and count Broadcast frames only.
Count IFG
Count IFG Bytes.
1= each frame’s minimum inter frame gap.
(IFG) bytes (12 per frame) are included in Ingress and Egress rate limiting
calculations.
0= IFG bytes are not counted.
Count Preamble
Count preamble Bytes.
1 = each frame’s preamble bytes (8 per frame) are included in Ingress and Egress rate
limiting calculations.
0 = preamble bytes are not counted.
