3.6 Console Port

UART4 on the USB port is reserved for the console port. An onboard EIA/TIA 232

transceiver provides true EIA/TIA 232 signaling on the transmit and receive signals. RTS

and CTS are available at the connector but are connected directly to the MPC5200 (3.3 V

logic).

3.7 CAN

The MPC5200 provides two CAN controllers (Version 2.0 A/B). External transceivers

and termination are required. Each CAN interface requires only a receive and a transmit

signal. CAN 1 is multiplexed on the I2C1 interface. CAN 2 is multiplexed on the Timer

port.

3.8 J1850

The MPC5200 provides a J1850 controller. The J1850 signals are multiplexed on the

Ethernet port. An external transceiver is required. Unfortunately, the specific bits are

used for the MII interface. If J1850 is used, the Ethernet PHY must be configured in 7-

wire mode and is limited to 10 Mbit/s. See section 3.10 for more details.

3.9 I/O

The various I/O ports on the MPC5200 may be configured in several modes.

Configuration is performed at the port-level by selecting one of several modes, individual

pins within the port are defined as a particular function in each mode. Certain

combinations are reserved. The I/O is optimized for automotive applications. Only valid

port configurations are shown. Invalid bits within valid configurations are shown in gray.
