Reserved. Read = 0b; Must write 0b.
ABORTD: Abort Disable Bit
0: MAC will abort when excessive delay is detected and update the transmit status vector.
1: MAC will attempt to transmit indefinitely as specified in IEEE 802.3.
EBBPD: Exponential Backoff after Back Pressure Disable Bit (Half-Duplex Only)
0: After incidentally causing a collision during back pressure, the MAC will use the exponential
backoff algorithm as specified in IEEE 802.3.
1: After incidentally causing a collision during back pressure, the MAC will immediately transmit
without using the exponential backoff algorithm.
EBD: Exponential Backoff Disable (Half-Duplex Only)
0: MAC will use the exponential backoff algorithm as specified in IEEE 802.3.
1: MAC will immediately retransmit following a collision.
RLPRE: Reject Long Preamble
0: MAC allows any length preamble as specified in IEEE 802.3.
1: MAC rejects packets with a preamble greater than 12 bytes in length.
PUREPRE: Pure Preamble Enforcement
0: No preamble checking is performed.
1: MAC will verify the content of the preamble to ensure it contains 0x55 and is error-free. Packets
with an invalid preamble will be rejected.
PADMD[1:0]: Pad Mode
Note: This bit field is ignored if PADEN is cleared to ‘0’. See Table 21 for a complete description.
PADEN: Pad Enable Bit (must be set to 0 in half-duplex operation)
Note: See Table 21 for a complete description.
CRCEN: CRC Enable Bit
Note: This bit must be set to ‘1’ if padding is enabled.
0: CRC will not be appended. Frames presented to the MAC must contain CRC.
1: CRC will be appended.
