7.2.4 False Carrier Sense Counter Register (FCSCR)
This counter provides information required to implement the “False Carriers” attribute within the MAU managed object
class of Clause 30 of the IEEE 802.3u specification.
7.2.5 Receiver Error Counter Register (RECR)
This counter provides information required to implement the “Symbol Error During Carrier” attribute within the PHY man-
aged object class of Clause 30 of the IEEE 802.3u specification.

False Carrier Event Counter:
This 8-bit counter increments on every false carrier event. This
counter sticks when it reaches its max count (FFh).

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 re-
ceive error detected. This event can increment only once per valid
carrier event. If a collision is present, the attribute will not incre-
ment. The counter sticks when it reaches its max count.
