I/O Connectivity and Port Routing
Most of the MCU’s I/Os are routed to the main mother board. These include the pins associated with the
FlexCAN, Ethernet, and LinFlex interfaces and other normal GPIO pins. The
MPC57XXXMB
provides
physical layer drivers for these communication protocols. See the
MPC57XXXMB
User Guide for the
correct jumper settings to enable and configure these drivers and associated circuits.
Table
7
lists the mapping from the MPC5746R device ports to the existing headers/ports on the
MPC57XXXMB
motherboard, and to the FlexCAN, Ethernet, UART and LinFlex drivers.
