A receive symbol error event is shown in
packet with the exception that all di-bits are substituted with the (01) pattern.

In 10M Mode, RXER will maintain low all the time due to False Carrier and symbol error is not supported by 10M
Mode. Different from 100M mode, RXD and CRSDV can transit once per 10 REFCLK cycles. After carrier sense
is de-asserted yet the FIFO data is not fully presented onto RXD, the CRSDV de-assertion and re-assertion also
follow this rule.

TXD[1:0] are synchronous to REFCLK. When TXEN is asserted, it indicates that TXD[1:0] contains valid data to
be transmitted. When TXEN is de-asserted, value on TXD[1:0] should be ignored. If an odd number of di-bits are
presented onto TXD[1:0] and TXEN, the final di-bit will be discarded by ADM7001.
