Communication Ports
1.4 Communication Ports
The MPC564EVB provides external interfaces for 2 SCI serial ports, 3 CAN ports and a 10/100T
ethernet port.
1.4.1 COM1 and COM2
The MPC564 processor has one queued serial multi-channel module (QSMCM) which provides
two serial communications interfaces (SCI/UART). These submodules communicate with the CPU
via a common slave bus interface unit (SBIU). The signals of COM1 and COM2 pass through
external Driver/Receivers to make the channels RS-232 compatible. An RS-232 serial cable with
DB9 connectors is included with the board. The signals of both channels are available on the
QSM_PORT connector. SCI0 (COM-1) is the “TERMINAL” channel used by dBUG for
communication with an external terminal/PC. The “TERMINAL” baud rate defaults to 19200.
Notes:
1.
COM ports provide connection pads 1 – 9 behind the DB9 cable connectors so the user
may modify operation of the serial connection. Each connection pad is numbered for the
associated serial connector pin. Each connection pad can be isolated from the others if
grouped above, by cutting the associated trace to the pad on the bottom side of the board.
See the MPC564EVB schematic.
2.
COM-2 has the JP1 DCE/DTE option, see below.
3.
RS232 translators available to COM3 and COM4 that are not required by user application
may be applied to other COM ports by isolating the MPC564 SCI signals to the RS232
transceiver and applying the associated RS232 level input or output to another COM port.
User should refer to the schematic diagrams of the board to make sure correct signals and
connections are isolated and reconnected for the new application.
