RX Alignment
Count of packets that have between 64 bytes and the maximum allowable
number of bytes and are not byte aligned and have a bad FCS. 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 Alignment Error Count Register (MAC_RX_ALIGN_CNT_x)
This register provides a counter of received packets with 64 bytes to the maximum allowable, and a
FCS error. The counter is cleared upon being read.
Note: For this counter, a packet with the maximum number of bytes that is not an integral number of
This counter will stop at its maximum value of FFFF_FFFFh.
Minimum rollover time at 100Mbps is approximately 481 hours.
