Port x MAC Receive 1024 to Max Byte Count Register (MAC_RX_1024_TO_MAX_CNT_x)

This register provides a counter of received packets between the size of 1024 to the maximum

allowable number bytes. The counter is cleared upon being read.

Note:

A bad packet is defined as a packet that has an FCS or Symbol error. For this counter, a packet

with the maximum number of bytes that is not an integral number of bytes (e.g. a 1518 1/2

byte packet) is counted.

31:0

RX 1024 to Max Bytes

Count of packets (including bad packets) that have between 1024 and the

maximum allowable number of bytes. The max number of bytes is 1518 for

untagged packets and 1522 for tagged packets. If Jumbo2K (bit 3) is set in

the Port x MAC Receive Configuration Register (MAC_RX_CFG_x), the max

number of bytes is 2048.

Note:

This counter will stop at its maximum value of FFFF_FFFFh.

Minimum rollover time at 100Mbps is approximately 5979 hours.
