OVRRIDE: Default Override
0: Settings for bits 5, 4, 3, 2, and 1 in TXCN will be ignored. MAC settings will take effect.
1: Settings for bits 5, 4, 3, 2, and 1 in TXCN will be applied. MAC settings will be overridden.
UNUSED. Read = 0b, Write = don’t care.
CRCENOV: CRC Enable
0: Disable CRC append on transmission.
1: Enable CRC append on transmission.
PADENOV: Pad Enable
0: Disable padding of short frames.
1: Enable padding of short frames.
TXPPKT: Transmit a PAUSE control packet
0: Normal packet transmission. Packet data will be obtained from the transmit buffer.
1: A PAUSE control packet with the value of TXPAUSEH:TXPAUSEL will be transmitted. Data in the
transmit buffer will not be accessed. PAUSE control packets are only valid in full-duplex mode.
BCKPRES: Apply Back Pressure
0: Normal packet transmission. Back pressure will not be applied.
1: Back pressure will be applied on transmission (only valid in half duplex mode).
FDPLXOV: Full Duplex Operation
Note: The transmit interface, MAC, and physical layer must be configured to the same duplex mode.
0: Transmit interface operates in half duplex mode.
1: Transmit interface operates in full duplex mode.
TXGO: Transmit Packet
Set this bit to ‘1’ to begin transmission of a packet.
Note: TXGO should not be set to one if both TXSTART and TXEND are zero (i.e., no data has been
added to the buffer).
TXBUSY: Packet Transmit Status
0: Packet Transmit is not in progress.
1: Packet Transmit is in progress.
