6.26 TOS Priority Map Registers (C0H~CFH)
Define the 6-bit or 3-bit of ToS field mapping to 2-bit priority queue number.
In 6-bit type, the Reg. 53H bit 7 is “1”, Reg. C0H bit [1:0] define the mapping for ToS value 0, Reg. 60H bit [3:2] define the
mapping for ToS value 1, … and so on, till Reg. CFH bit [7:6] define ToS value 63.
In 3-bit type, Reg. C0H bit [1:0] defines the mapping for ToS value 0, Reg. 60H bit [3:2] defines the mapping for ToS value 1 …
and so on, and till Reg. C1H bit [7:6] define ToS value 7.
