MPC8272ADS User Guide
Fast-Ethernet 2 Transmit Clock. When the Ethernet port is
enabled, this clock (25 MHz for 100 Mbps, 2.5 MHz for 10 Mbps)
is normally extracted from the received data and driven to the
PowerQUICC II to qualify out coming transmit data. In Slave mode
(not used with this application) this clock should be input to the
DM9161.
When the Ethernet port is disabled, this line is tristated and may be
used for any available function of PC16
PowerQUICC II’s Port C 13 Parallel I/O line. May be used to any
of its available functions.
USB RP Line. When the USB port is enabled, this line is connected
to the receive positive line of the USB tranceiver. When this port is
disabled, this signal is tristated and may be used for any available
function of PC11.
Fast-Ethernet Port Management Data Clock. This slow clock (S/W
generated) qualifies the management data I/O to read / write the
DM9161’s internal registers.
When the Ethernet port is disabled, this line may be used for any
available function of PC19.
Fast-Ethernet Port Management Data I/O. This signal serves as
bidirectional serial data line, qualified by FETHMDC, to allow read
/ write the DM9161’s internal registers.
When the Ethernet port is disabled, this line may be used for any
available function of PC18.
USB RN Line. When the USB port is enabled, this line is
connected to the receive negative line of the USB tranceiver.
When this port is disabled, this signal is tristated and may be used
for any available function of PC10.
RS232 Port 2 Carrier Detect (L). Connected via RS232 transceiver
to RS232 DTR2# input, allowing detection of a connected terminal
to this port. This line is simply a PI/O input line to the PowerQUICC
II.
When RS232 Port 2 is disabled, this line is tristated and may be
used for any available function of PC8.
