PADMD1[7] PADMD0[6] PADEN[5] CRCEN[4]
PHEADER: Proprietary Header Select Bit
0: No proprietary header exists on the front of IEEE 802.3 frames.
1: Four bytes of proprietary header information exist on the front of IEEE 802.3 frames. These bytes
will be ignored by the CRC function.
Reserved. Read = 0b; Must write 0b.
LENCHK: Frame Length Checking Enable Bit
0: Frame length checking is disabled.
1: Transmit and receive frame lengths are compared to the Length/Type field. If the Length/Type
field represents a length then the check is performed. Mismatches are reported in the Transmit/
Receive status vectors.
FLLDPLX: Full-Duplex Mode Enable Bit
0: MAC operates in half-duplex mode.
1: MAC operates in full-duplex mode.
Indirect Register 2. MACCF: MAC Configuration Register (Continued)
