For each entry equal to one in the Transmit PFC Pause Register [15:8], the pause quantum associated with that entry will be zero.

Bits 7:0 – PEV[7:0] Priority Enable Vector

If NCR.TXPBPF =1, then the priority enable vector of the PFC priority based pause frame will be set equal to the value stored in this register [7:0].
