Provides a timing reference to the PHY for data transfers on the
EMDIO signal.
Note: Not available on MCF5214 and MCF5216
Transfers control information between the external PHY and the
media access controller.
Note: Not available on MCF5214 and MCF5216
Provides a timing reference for ERXDV, ERXD[3:0], and
ERXER.
Note: Not available on MCF5214 and MCF5216
Contain the Ethernet input data transferred from the PHY to the
media access controller (when ERXDV is asserted in MII mode).
Note: Not available on MCF5214 and MCF5216
Ethernet input data transferred from the PHY to the media
access controller (when ERXDV is asserted).
Note: Not available on MCF5214 and MCF5216
Asserted to indicate that the PHY has valid nibbles present on
the MII.
Note: Not available on MCF5214 and MCF5216
Indicates (when asserted with ERXDV) that the PHY has
detected an error in the current frame.
Note: Not available on MCF5214 and MCF5216
Provides a timing reference for ETXEN, ETXD[3:0], and ETXER.
Note: Not available on MCF5214 and MCF5216
Contain the serial output Ethernet data.
Note: Not available on MCF5214 and MCF5216
Serial output Ethernet data.
Note: Not available on MCF5214 and MCF5216
Indicates when valid nibbles are present on the MII.
Note: Not available on MCF5214 and MCF5216
Asserted (for one or more E_TXCLKs while ETXEN is also
asserted) to cause the PHY to send one or more illegal symbols.
Note: Not available on MCF5214 and MCF5216
Driven by an external clock except when used as a connection
to the external crystal.
Supply power and ground to Flash array.
Used for Flash stress testing.
Provide the external interface to the timer A functions.
Provide the external interface to the timer B functions.
Negative supply.
External interrupt sources.
