Signal Descriptions
14.2.6.6 Collision (ECOL)
The ECOL input is asserted upon detection of a collision and remains asserted while the collision persists.
This signal is not defined for full-duplex mode.
This pin can also be configured as GPIO PEH4.
14.2.6.7 Receive Clock (ERXCLK)
The receive clock (ERXCLK) input provides a timing reference for ERXDV, ERXD[3:0], and ERXER.
This pin can also be configured as GPIO PEH3.
14.2.6.8 Receive Data Valid (ERXDV)
Asserting the receive data valid (ERXDV) input indicates that the PHY has valid nibbles present on the
MII. ERXDV should remain asserted from the first recovered nibble of the frame through to the last
nibble. Assertion of ERXDV must start no later than the SFD and exclude any EOF.
This pin can also be configured as GPIO PEH2.
14.2.6.9 Receive Data 0 (ERXD0)
ERXD0 is the Ethernet input data transferred from the PHY to the media-access controller when ErXDV
is asserted. This signal is used for 10 Mbps Ethernet data. This signal is also used for MII mode Ethernet
data in conjunction with ERXD[3:1]. This pin can also be configured as GPIO PEH1.
14.2.6.10 Carrier Receive Sense (ECRS)
ECRS is an input signal which, when asserted, signals that transmit or receive medium is not idle, and
applies to MII mode operation.
This pin can also be configured as GPIO PEH0.
14.2.6.11 Transmit Data 1–3 (ETXD[3:1])
These pins contain the serial output Ethernet data and are valid only during assertion of ETXEN in MII
mode.
These pins can also be configured as GPIO PEL[7:5].
14.2.6.12 Transmit Error (ETXER)
When the ETXER output is asserted for one or more E_TXCLKs while ETXEN is also asserted, the PHY
sends one or more illegal symbols. ETXER has no effect at 10 Mbps or when ETXEN is negated, and
applies to MII mode operation.
These pins can also be configured as GPIO PEL4.
14.2.6.13 Receive Data 1–3 (ERXD[3:1])
These pins contain the Ethernet input data transferred from the PHY to the media-access controller when
ERXDV is asserted in MII mode operation.
These pins can also be configured as GPIO PEL[3:1].
