Register 144 (0x90): TOS Priority Control Register 0
The IPv4/IPv6 TOS priority control registers implement a fully decoded 64 bit differentiated services code point (DSCP) register used to
determine priority from the 6 bit TOS field in the IP header. The most significant 6 bits of the TOS field are fully decoded into 64
possibilities, and the singular code that results is mapped to the value in the corresponding bit in the DSCP register.

The unit period for calculating Ingress Rate Limit
00 = 16 ms
01 = 64 ms
1x = 256 ms
Enable Queue-based Egress Rate Limit
0 = port-base Egress Rate Limit (default)
1 = queue-based Egress Rate Limit
1 = enable source port PVID tag insertion or non-
insertion option on the egress port for each source
port PVID based on the ports registers control 8.
0 = disable, all packets from any ingress port will be
inserted PVID based on port register control 0 bit 2.

IPv4 and IPv6 mapping
The value in this field is used as the frame’s priority
when bits[7:2] of the frame’s IP TOS/DiffServ/Traffic
Class value is 0x03.
