Description
Reserved
Transmit TX descriptor 3
If this bit is enabled, MAC will begin to transmit data that are stored in TX
buffer. In former, data had been written to TX descriptor3. This bit will be
cleared by hardware when MAC finished the transmission.
1= enable
0= disable
Reserved
TX Packet Length (unit: byte)
Driver set this field to indicate AX88780 how many bytes will be
transmitted.

RX Buffer Monitor Enable
When this bit is enable, MAC will monitor the status of the receive buffer.
1 = enable
0 = disable
Reserved.
RX Packet TCP/IP Checksum
When this bit is set, AX88780 will check the checksum of the received
packet that is IP, TCP or UDP packet. If there is checksum error, AX88780
will drop the packet and RXCHKSUMCNT counter will add 1.
1 = enable
0 = disable
Reserved
RX Buffer Protection
When this bit is enabled, MAC will protect the RX buffer to avoid overrun.
For normal operation, this bit should be enabled in initial stage.
1= enable
0= disable
