Priority Control Register 1 (Offset 0x0480): TOSR1
This register contains the TOS priority control for the switch function.
The IPv4/Ipv6 TOS priority control registers implement a fully decoded 64 DSCP (Differentiated Services Code Point)
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 bits in
the DSCP register to determine the priority.
