Attribute
I/O, T.S.
Fast-Ethernet Transmit Enable (H). The MSC8101 will assert
(High) this line, to indicate data valid on the FETHTXD(3:0) lines.
When the Fast-Ethernet port is disabled, this line may be used for
any available function of PB29.
I/O, T.S.
Fast-Ethernet Receive Error (H). When this signal is asserted
(High) by the LXT970, while the Ethernet port is enabled and
FETHRXCK goes high, it indicates that the port is receiving
invalid data symbols from the network.
When the Ethernet port is disabled, this line is tristated and may
be used for any available function of PB28.
I/O, T.S.
Fast-Ethernet Port Collision Detected (H). When this signal is
asserted (High) by the LXT970, while the ethernet port is enabled,
it indicates a Collision state over the line. When the LXT970 is in
Full-Duplex mode, this line is inactive.
When the Ethernet port is disabled, this line is tristated and may
be used for any available function of the PB27.
I/O, T.S.
Fast-Ethernet Carrier Sense (H). When this signal is asserted
(High), while the Ethernet port is enabled and the LXT970 is in
half-duplex mode, it indicates that either the transmit or receive
media are non-idle. When the LXT970 is in either full-duplex or
repeater operation, it indicates that the receive medium is non-
idle.
When the Ethernet port is disabled, this line may be used for any
available function of PB26.
I/O, T.S.
Fast Ethernet Transmit Data (3:0). This is the MII transmit data
bus. The MSC8101 drives these lines according to rising edge of
FETHTXCK.
When the ethernet port is disabled, these lines may be used for
any available respective function.
I/O, T.S.
Fast Ethernet Receive Data (3:0). This is the MII receive data
bus. The LXT970 drives these lines according to rising edge of
FETHRXCK.
When the ethernet port is disabled, these lines are tristated and
may be used for any available respective parenthesized function.
