Communication Ports
JP1 – COM2 DCE/DTE Option:
1
COM-2 is optioned as a DCE type RS232 connection by default (same as COM-1). This allows
direct connection to a standard 9 pin PC COM serial port.
1
COM-2 DTE option. This requires a NULL modem adapter to connect to a standard 9 pin PC
COM serial port.
AT1/2, AR1/2 - Serial Port Configuration
The AT1, AT2, AR1 and AR2 cut-away options provide a means of isolating the individual SCI
RXD and TXD signals from the RS232 interface translator device (U10) and COM port operation.
This allows the SCI channels to be used for other purposes, possibly on the QSM port connector.
Following is a table of the SCI signals and AT/R_ positions used for enabling RS232 and COM
port operation. Note: 2mm header maybe installed after cutaways are cut to allow jumper option.

1.4.2 CAN PORTs and Options
1
The MPC564EVB board provides 3 CAN transceivers with I/O ports: CAN_A, CAN_B, and
CAN_C. CAN_A is supported by the PC33394 Power Oak CAN transceiver. The CAN_B and
CAN_C ports are supported by Philips PCA82C250 1M Baud CAN transceivers. The MPC564
CAN_A port is directly interfaced to the Power Oak transceiver and can not be isolated easily. The
MPC564 CAN_B and C ports are interfaced to the MPC564 TOUCAN channels B and C by option
jumpers B_RX, C_TX, and C_RX.
