PRODUCTION DATA.
This counter provides information required to implement the “Symbol Error During Carrier” attribute within the PHY managed object class of Clause 30 of the IEEE 802.3u specification.
BIT | BIT NAME | DEFAULT | DESCRIPTION |
---|---|---|---|
15:8 | RESERVED | 0, RO | RESERVED: Writes ignored, Read as 0 |
7:0 | RXERCNT[7:0] | 0, RO/COR | RX_ER Counter: |
When a valid carrier is present and there is at least one occurrence of an invalid data symbol, this 8-bit counter increments for each receive error detected. This event can increment only once per valid carrier event. If a collision is present, the attribute will not increment. The counter sticks when it reaches its max count. |
