Bit [0]
1 - Flow Control Off
0 - Flow Control On
When Flow Control On:
In half duplex mode, the MAC transmitter applies back pressure for flow control.
In full duplex mode, the MAC transmitter sends Flow Control frames when
necessary. The MAC receiver interprets and processes incoming flow control
frames. The Flow Control Frame Received counter is incremented whenever a
flow control is received.
When Flow Control off:
In half duplex mode, the MAC Transmitter does not assert flow control by sending
flow control frames or jamming collision.
In full duplex mode, the Mac transmitter does not send flow control frames. The
MAC receiver does not interpret or process the flow control frames. The Flow
Control Frame Received counter is not incremented.
Bit [1]
1 - Half Duplex - Only 10/100 mode
0 - Full Duplex
Bit [2]
1 - 10 Mbps
0 - 100 Mbps
Bit [4:3]
00 - Automatic Enable Auto Neg. This enables hardware state machine for
auto-negotiation.
01 - Limited Disable auto Neg. This disables hardware for speed auto-
negotiation. Poll MII for link status.
10 - Link Down. Disable auto Neg. state machine and force link down
(disable the port)
11 - Link Up. User ERC1 [2:0] for config.
Bit [5]
Asymmetric Flow Control Enable
0 - Disable asymmetric flow control
1 - Enable asymmetric flow control
Asymmetric Flow Control Enable. When this bit is set and flow control is on
(bit [0] = 0, don't send out a flow control frame. But MAC receiver interprets
and process flow control frames. Default is 0
Bit [7:6]
SS - Spanning tree state Default is 11
00 – Blocking: Frame is dropped
01 - Listening: Frame is dropped
10 - Learning: Frame is dropped. Source MAC address is learned.
11 - Forwarding: Frame is forwarded. Source MAC address is learned.
