0-FFh Receive pause timer value. These bits allow the contents of the receive pause timer to be
observed. The receive pause timer is loaded with FF00h when the EMAC sends an outgoing pause
frame (with pause time of FFFFh). The receive pause timer is decremented at slot time intervals. If
the receive pause timer decrements to 0, then another outgoing pause frame is sent and the
load/decrement process is repeated.

enabled.
