Controller Area Network (FlexCAN)
25.1 FlexCAN Introduction
The FlexCAN module is a communication controller implementing the CAN protocol
according to the CAN 2.0B protocol specification. A general block diagram is shown in
Figure
including two embedded memories, one for storing Message Buffers (MB) and another one
for storing Rx Individual Mask Registers. The functions of the sub-modules are described
in subsequent sections.
