Default
Bit 6: Uncontrolled Control Frame Reject (UCFR) When set to 1, Control Frames other than Pause Frames are
allowed. When this bit is equal to zero, nonpause control frames are rejected.
Bit 5: Control Frame Reject (CFRR) When set to 1, control frames are allowed. When this bit is equal to zero, all
control frames are rejected.
Bit 4: Length Error Reject (LERR) When set to 1, frames with an unmatched frame length field and actual
number of bytes received are allowed. When equal to zero, only frames with matching length fields and actual
bytes received will be allowed.
Bit 3: CRC Error Reject (CRCERR) When set to 1, frames received with a CRC error or MII error are allowed.
When equal to zero, frames with CRC or MII errors are rejected.
Bit 2: Dribbling Bit Reject (DBR) When set to 1, frames with lengths of noninteger multiples of 8 bits are allowed.
When equal to zero, frames with dribbling bits are rejected. The dribbling bit setting is only valid only if there is not
a collision or runt frame.
Bit 1: MII Error Reject (MIIER) When set to 1, frames are allowed with MII Receive Errors. When equal to zero,
frames with MII errors are rejected.
Bit 0: Broadcast Frame Reject (BFR) When set to 1, broadcast frames are allowed. When equal to zero,
broadcast frames are rejected.
