while supporting communications rates to 1 Mbaud. The PHY provides slope control reducing

radio frequency interference (RFI) while providing a wide common-mode range input protecting

against electro-magnetic interference (EMI). The PHY also provides short-circuit protection to

battery and ground. Refer to the PCA82C250 data sheet for further details.

The FlexCAN module in the MCF52259 provides support for the CAN protocol. The FlexCAN

module supports standard and extended identifier (ID) message formats specified in the CAN

protocol specification, revision 2.0, part B. The CAN module is disabled out of reset by default

and must be configured by user application before use.

I/O CONNECTORS

The CMM-52259 applies several IO connectors arranged around the perimeter of the board

providing access to most MCU signals. The BDM_PORT header is dedicated to development

access. The figures below show signal assignment for each IO connector. With the exception

of the BDM_PORT header at J4, the IO headers are not populated in default configurations.
