15:0 | RX_PAUSETIMER | R/W | 0h | 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 Enet port 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. This register is for 802.3 Based flow control and is not used for 802.1Qbb Priority Based Flow Control (PFC). |
