BIT DESCRIPTION
Force speed to 10M and can transmit data.
0 = Normal operation.
1 = Force 10M and can transmit data.
Tx NLP enabled.
0 = Disable normal link pulse function.
1 = Enable normal link pulse function.
Heartbeat enable.
0 = Disable heartbeat function.
1 = Enable heartbeat function.
Jabber function enable.
0 = Disable Jabber function.
1 = Enable Jabber function.
Repeater Mode Enable. To configure the IP100 in repeater mode,
reprt_en must be a logic 1. If reprt_en is a logic 0, the IP100 is in
NIC mode.
Reserved for future use.
