16.4 General description
UM10398
User manual
Controller Area Network (CAN) is the definition of a high performance communication
protocol for serial data communication. The C_CAN controller is designed to provide a full
implementation of the CAN protocol according to the CAN Specification Version 2.0B. The
C_CAN controller allows to build powerful local networks with low-cost multiplex wiring by
supporting distributed real-time control with a very high level of security.
The CAN controller consists of a CAN core, message RAM, a message handler, control
registers, and the APB interface.
For communication on a CAN network, individual Message Objects are configured. The
Message Objects and Identifier Masks for acceptance filtering of received messages are
stored in the Message RAM.
All functions concerning the handling of messages are implemented in the Message
Handler. Those functions are the acceptance filtering, the transfer of messages between
the CAN Core and the Message RAM, and the handling of transmission requests as well
as the generation of the module interrupt.
The register set of the CAN controller can be accessed directly by an external CPU via the
APB bus. These registers are used to control/configure the CAN Core and the Message
Handler and to access the Message RAM.
