Cortex-M3 Controller Area Network
This device has two Cortex-M3 CAN peripherals. CAN is a serial communications protocol that efficiently
supports distributed real-time control with a high level of security. The CAN module supports bit rates up
to 1 Mbit/s and is compliant with the CAN 2.0B protocol specification.

Functional Overview
CAN performs CAN protocol communication according to ISO 11898-1 (identical to Bosch
®
CAN protocol
specification 2.0 A, B). The bit rate can be programmed to values up to 1 Mbit/s. Additional transceiver
hardware is required for the connection to the physical layer (CAN bus).
hardware is required for the connection to the physical layer (CAN bus).
For communication on a CAN network, individual message objects can be configured. The message
objects and identifier masks are stored in the Message RAM. All functions concerning the handling of
messages are implemented in the message handler. Those functions are: acceptance filtering, the transfer
of messages between the CAN Core and the Message RAM, and the handling of transmission requests.

The register set of the CAN is accessible directly by the CPU via the module interface. These registers are
used to control/configure the CAN Core and the message handler, and to access the message RAM.
