IEEE 802.3x
transmit flow
control enable
RW 1: Enable transmit flow control based on auto-negotiation results
0: Will not enable transmit flow control no matter what the auto-
negotiation result is
Note: This bit is global and has higher priority than NWAY result.
16.4
IEEE 802.3x
receive flow
control enable
RW 1: When the RTL8306SD/RTL8306SDM receives a pause control
frame, it has the ability to stop the next transmission of a normal
frame until the timer is expired based on the auto negotiation
result
1
0: Will not flow control received frames no matter what the auto-
negotiation result is
Note: This bit is global and has higher priority than NWAY result.

0: Do not drive LED pins of port 4 for special application. In UTP
application, this bit should be set to 1 to drive LEDs of port 4
