Receive Data[3:0] (RXD[3:0])
RXD[3:0] transitions synchronously with respect to RXC. For each clock period in which RXDV is asserted, RXD[3:0]
transfers a nibble of recovered data from the PHY.
Receive Error (RXER)
RXER is asserted for one or more RXC periods to indicate that a Symbol Error (e.g., a coding error that a PHY is capable
of detecting, and that may otherwise be undetectable by the MAC sub-layer) was detected somewhere in the frame
presently being transferred from the PHY.
RXER transitions synchronously with respect to RXC. While RXDV is de-asserted, RXER has no effect on the MAC.
Carrier Sense (CRS)
CRS is asserted and de-asserted as follows:
In 10Mbps mode, CRS assertion is based on the reception of valid preambles. CRS de-assertion is based upon
the reception of an end-of-frame (EOF) marker.
In 100Mbps mode, CRS is asserted when a start-of-stream delimiter or /J/K symbol pair is detected. CRS is de-
asserted when an end-of-stream delimiter or /T/R symbol pair is detected. Additionally, the PMA layer de-asserts
CRS if IDLE symbols are received without /T/R.
Collision (COL)
COL is asserted in half-duplex mode whenever the transmitter and receiver are simultaneously active on the line. This is
used to inform the MAC that a collision has occurred during its transmission to the PHY.
COL transitions asynchronously with respect to TXC and RXC.
MII Signal Diagram
The KSZ8051MNL MII pin connections to the MAC are shown in the following figure.
