ATM Transmit Enabled (L). When this signal is asserted (Low),
while the ATM port is enabled and ATMTFCLK is rising, an octet of
data, ATMTXD(7:0), is written into the transmit FIFO of the
PM5384. When the ATM port is disabled, this line may be used for
any available function of PA31.
Fast-Ethernet Port 1 Collision Detected (H). When this signal is
asserted (High) by the DM9161, while the ethernet port is enabled,
it indicates a Collision state over the line. When the DM9161 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 PA31.
ATM Transmit Cell Available (H). When this signal is asserted
(High), while the ATM port is enabled, it indicates that the transmit
FIFO of the PM5384 is empty and ready to except a new cell.
When negated, it may show either that the transmit FIFO is Full or
close to Full, depending on PM5384 internal programming.
When the ATM port is disabled, this line may be used for any
available function of PA30.
Fast-Ethernet 1 Carrier Sense (H). When this signal is asserted
(High), while the Ethernet port is enabled and the DM9161 is in
half-duplex mode, it indicates that either the transmit or receive
media are non-idle. When the DM9161 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 PA30.
ATM Transmit Start Of Cell (H). When this signal is asserted (High)
by the PowerQUICC II, while the ATM port is enabled, it indicates
to the PM5384 the start of a new ATM cell over ATMTXD(7:0), i.e.,
the 1’st octet is present there.
When the ATM port is disabled, this line may be used for any
available function of PA29.

enabled, this signal will be asserted (High) by the PowerQUICC II
when an error is discovered in the transmit data stream. When the
port is operation at 100 Mbps, the DM9161 responds by sending
invalid code symbols on the line.
When the Ethernet port is disabled, this line may be used for any
available function of PA29.
