RX Pause Timer Value - This field allows the contents of the receive
pause timer to be observed (and written in test mode).
The receive pause timer is loaded with 0xFF00 when the
CPGMAC_SL sends an outgoing pause frame (with pause time of
0xFFFF).
The receive pause timer is decremented at slot time intervals.
If the receive pause timer decrements to zero, then another outgoing
pause frame will be sent and the load/decrement process will be
repeated.
