The following table is the Ethernet Configuration and Status Register description for Port 0
(as identified by the register address). The Ethernet Configuration and Status Register
description for Ports 1 to 31 are identical to Port 0. Port 1 registers start at 0x4100, Port 2
registers start at 0x4200, and so on. Port 31 registers start at 0x5F00 per the

Port 0 MAC Configuration and Status Registers.
Port 0 Configuration Register #1
Transmit Enable:
0 - Transmission of frames is prevented
1 - The port is allowed to transmit frames to the system
Synchronized Transmit Enable:
1 - Transmit Enable is synchronized to the transmit stream
Receive Enable:
0 - Reception of frames is prevented
1 - The port is allowed to receive frames from the PHY
Synchronized Receive Enable:
1 - Receive Enable is synchronized to the receive stream.
Transmit Pause Frame Generation Enable:
0 - Prevents the transmit port MAC Control from sending Flow Control
frames
1 - Allows the transmit port MAC Control to send PAUSE Control frames
when requested by the system
Receive Pause Frame Processing Enable: Setting this bit will cause
the Receive port MAC Control to detect and act on PAUSE Control
frames. Clearing this bit causes the Receive port MAC Control to ignore
PAUSE Flow Control frames.
Reserved
Loopback Mode:
0 - Results in normal operation
1 - The port will “Loopback” all data received from the Egress FIFO
controller to the Ingress FIFO controller, i.e. Data from the SPI-3 is looped
back at the Ethernet interface
Reserved
Reset Tx Function:
1 - The Transmit Function block is placed in reset. This block performs the
frame transmission protocol.
