TX Pause Timer Value - This field allows the contents of the transmit
pause timer to be observed (and written in test mode).
The transmit pause timer is loaded by a received (incoming) pause
frame, and then decremented, at slottime intervals, down to zero at
which time CPGMAC_SL transmit frames are again enabled.
