Advanced Control Registers (Registers 96-198)
The IPv4/IPv6 TOS Priority Control Registers implement a fully decoded, 128-bit DSCP (Differentiated Services Code
Point) register set that is used to determine priority from the ToS (Type of Service) 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 compared
against the corresponding bits in the DSCP register to determine the priority.
Register 96 (0x60): TOS Priority Control Register 0
Register 97 (0x61): TOS Priority Control Register 1
Register 98 (0x62): TOS Priority Control Register 2
