Receive Length Error Count, XON Received Count

13.7.15Receive Length Error Count

RLEC (04040h; R)

This register counts receive length error events. A length error occurs if an incoming packet passes the filter criteria but is undersized or oversized. Packets less than 64 bytes are undersized. Packets over 1522 bytes are oversized if LongPacketEnable is 0b (RCTL.LPE). If LongPacketEnable (LPE) is 1b, then an incoming packet is considered oversized if it exceeds 16384 bytes.

If receives are not enabled, this register does not increment. These lengths are based on bytes in the received packet from <Destination Address> through <CRC>, inclusively.

13.7.16XON Received Count

XONRXC (04048h; R)

This register counts the number of valid XON packets received. XON packets can use the global address, or the station address. This register only increments if receives are enabled.
