7.2 Extended Registers - Page 0

7.2.1 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.

7.2.2 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.

7.2.3 100 Mb/s PCS Configuration and Status Register (PCSR)

This register contains control and status information for the 100BASE Physical Coding Sublayer.

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.
