Section 5
Serial I/O
This chapter describes the Pm8560 serial ports and baud rate generators.
SERIAL PORTS
EIA-232 Serial Port:
The serial port from the MPC8560 is available at the front panel, connector P14, and the
DMC; or connector P13 when a CT bus is present. This serial port is for boot flash program-
ming, initial setup, and debug. See
Table 5-1
for the front panel mini-B pin assignments.
View the P14 pin assignments in
Table 6-2
and P13 pin assignments in
Table 7-4
.
Caution:
Although a serial port is available at the front panel, P14 connector, and DMC; only one
should be connected at any given time. Connecting more than one serial port would create
a conflict and the serial port may not operate correctly.
Second Serial Port:
This port is routed from MPC8560 to connector P14, pin assignments are shown in
Table 6-
2
.
Serial lines consist of serial data in and serial data out for each port only. The ports do not
include handshaking. A transceiver translates the serial lines to EIA-232. This provides:
• Operation from a single 3.3 volt supply
• Two drivers and two receivers in one package
• Over +/-10 kilovolt ESD protection
• Operating up to 120 kilobaud
• Auto shutdown automatically enters a low-power shutdown mode when the EIA-232
cable is removed or the driving UART transmitters are inactive for more than 30 seconds.
Serial Port Connector P17 and Cable
Connector P17 provides the serial port access through the front panel, see
Table 5-1
for pin
assignments. The manufacturer part number for this nine-pin connector is (Molex) 54819-
0578. Use Emerson cable assembly C0003555-00 (
Fig. 5-1
).
