Advanced Control Registers
The IPv4 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 compared against the
corresponding bit in the DSCP register. f the register bit is a 1, the priority is high; if it is a 0, the priority is low.
