MainCAN and AuxCAN Bus
The FlexCAN module is a communication controller implementing the CAN protocol according to the
CAN 2.0B protocol specification, which supports both standard and extended message frames. A number
of Message Buffers (32) is also supported. Please refer to the MPC560xB reference manual for a detailed
description. The Freescale system basis chip MCZ33905D with one CAN is used as the main CAN
hardware interface, and the Freescale chip MCZ33902 is used as the auxiliary hardware interface. Jumpers
(J704, J705) and (J900, J901) define the middle or end node.
4.9
LIN bus interfaces
The LINFlex (Local Interconnect Network Flexible) controller interfaces the LIN network and supports
the LIN protocol versions 1.3, 2.0 and 2.1, and J2602 in both Master and Slave modes. Please refer to the
MPC560xB reference manual for a detailed description. The Freescale system basis chip MC33905D, with
two LIN bus physical interfaces, provides an additional possibility for connection. Both the LIN_1 and
LIN_2 interfaces can be configured as master or slave by jumpers (J706, J707).

Board Set-up Guide
The board is designed to be supplied either by the UNI-3 interface or by using the on-board J700 connector,
with a power supply voltage from 8 to 18V. When using the board as a stand-alone EVB, connect the power
supply to J700. In the case of board operation with the power stage, it is recommended to supply the board
using the UNI-3 interface.
The MPC560xB Controller Board is designed for operation with the Freescale MC33937A based 3-Phase
low-voltage power stage; see
Figure 11
