Memory Maps and Bit Descriptions
Reset Rx Function:
1 - The Receive Function block is placed in reset. This block performs the
receive frame protocol.
Reset Tx MAC Control:
1 - The Transmit port MAC Control block is placed in reset. This block
multiplexes data and Control frame transfers. It also responds to XOFF
PAUSE Control frames.
Reset Rx MAC Control:
1 - The Receive port MAC Control block is placed in reset. This block
detects Control frames and contains the pause timers.
Reserved
Simulation Reset:
1 - This bit will reset those registers, such as the random back-off timer,
which are not controlled by normal resets (for simulation only).
Soft Reset: Setting this bit will put all modules within the MAC in reset,
except the Host Interface. The Host Interface is reset via Lead Hardware
reset (RESET). Soft Reset should be performed in the absence of traffic.
Port 0 Configuration Register #2
Full-duplex:
0 - The port will operate in Half-Duplex mode
1 - The port will operate in Full-Duplex mode
CRC Enable:
0 - Frames presented to the port MAC must have a valid length and
contain a valid CRC
1 - The port will append a CRC on all frames
If the configuration bit PAD/CRC Enable is set, CRC Enable is ignored.
Note: Used for frames transmitted from the Ethernet (Egress) ports only
PAD / CRC Enable:
0 - Frames presented to the port’s MAC must have a valid length and
contain a CRC
1 - The port will pad all short frames and append a CRC to every frame
whether or not padding was required
Note: Used for frames transmitted from the Ethernet (Egress) ports only
Reserved
Length Field Checking:
0 - No length field checking is performed
1 - The port will check if the frame length field matches the actual data
field length
