MDC Clock Divide Factor
This field defines the divide factor of host clock. AX88780 will refer to this field
and generate a low speed clock to PHY.
Reserved
TX Fail Counter
This field records the number of transmitted error for TX packet. The value will
be rounded back to 0x0000 if it exceeds 0xFFFF.
Reserved
EEPROM Data Port
The data to or from EEPROM is set in this field.
If the RXCHKSUM field of RX_CFG register is set to ‘1’, MAC will check the
checksum of IP, TCP or UDP packet. Whenever there is checksum error
detected, this field will be added one. The value will be rounded back to 0x0000
if it exceeds 0xFFFF.
Reserved
RX CRC32 Error Counter
MAC checks the received packet. If there is a CRC error detect, this field will
be added one. The value will be rounded back to 0x0000 if it exceeds 0xFFFF.
