CAN MODULE
The CAN module is a protocol controller that converts
between raw digital data and CAN message packets.
The main functional block of the CAN module is shown
in Figure 2-1 and consists of:
CAN protocol engine
Buffers, masks and filters
The module features include:
Implementation of the CAN protocol
Double-buffered receiver with two separate
receive buffers
One full-acceptance mask (standard and
extended)
Two full-acceptance filters (standard and
extended)
One filter for each receive buffer
Three prioritized transmit buffers for transmitting
predefined message types
Automatic wake-up on bus traffic function
Error management logic for transmit and receive
error states
Low-power SLEEP mode
