Figure 94. CAN network topology
CAN 2.0B active core
The beCAN module handles the transmission and the reception of CAN messages fully
autonomously. Standard identifiers (11-bit) and extended identifiers (29-bit) are fully
supported by hardware.
Control, status and configuration registers
The application uses these registers to:
●
●
●
●
●
Tx mailboxes
Two transmit mailboxes are provided to the software for setting up messages. The
Transmission Scheduler decides which mailbox has to be transmitted first.
Acceptance filters
The beCAN provides six scalable/configurable identifier filter banks for selecting the
incoming messages the software needs and discarding the others.
Receive FIFO
The receive FIFO is used by the CAN controller to store the incoming messages. Three
complete messages can be stored in the FIFO. The software always accesses the next
available message at the same address. The FIFO is managed completely by hardware.
