RX CRC
Count of packets that have between 64 and the maximum allowable number
of bytes and have a bad FCS, but do not have an extra nibble. The max
number of bytes is 1518 for untagged packets and 1522 for tagged packets.
If Jumbo2K (bit 3) is set in the
(MAC_RX_CFG_x), the max number of bytes is 2048.
Note:
Port x MAC Receive CRC Error Count Register (MAC_RX_CRCERR_CNT_x)
This register provides a counter of received packets that with CRC errors. The counter is cleared upon
being read.
This counter will stop at its maximum value of FFFF_FFFFh.
Minimum rollover time at 100Mbps is approximately 137 hours.
