RS_RXD2 (PD22)
I/O, T.S.
When RS232 port #2 is enabled, this signal is the receive data line
for that port. When this port is disabled, this signal is tristated and
may be used to any available alternate function for PD22.
C10
RS_TXD2 (PD21)
I/O, T.S.
When RS232 port #2 is enabled, this signal is the transmit data line
for that port. When this port is disabled, this signal may be used to
any available alternate function for PD21.

FETH1RXDV (PB30)
I/O, T.S.
Fast-Ethernet 1 Receive Data Valid (H). When this signal is
asserted (High) while the Fast Ethernet port is enabled and
FETHRXCK goes high, it indicates that data is valid on the MII
Receive Data lines - FETHRXD(3:0).
When the Fast Ethernet port is disabled, this line is tristated and
may be used for any available function go PB30.
C16
FETH1RXER (PB28)
I/O, T.S.
Fast-Ethernet 1 Receive Error (H). When this signal is asserted
(High) by the DM9161, 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.
C17
FETH1TXER (PB31)
I/O, T.S.
Fast-Ethernet 5 1 Transmit Error (H). When the Ethernet port is
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 PB31.
