3 BLOCK DIAGRAM
The design consists of the functional blocks described below (see Figure 8.5-1):
CAN Core
CAN Protocol Controller and Rx/Tx Shift Register for serial/ parallel conversion of messages.
Message RAM
Stores Message Objects and Identifier Masks.
Registers
All registers used to control and configure the C_CAN module.
Message Handler
State Machine that controls the data transfer between the Rx/Tx Shift Register of the CAN Core and the Message
RAM as well as the generation of interrupts as programmed in the Control and Configuration Registers.
Module Interface
The C_CAN module is delivered with three different interfaces. An 8-bit interface for the Motorola HC08 controller
and two 16-bit interfaces to the AMBA APB bus from ARM. This can easily be replaced by a user-defined module
interface.
