Control Area Network (CAN) is a serial communication protocol with high level of security. Each
node is master on the bus but only one at a time is able to send a message.
CANIF is a 32-bit interface for CAN channels. Each channel provides the following services:
These services, with the exception of message filtering and message handling, are described in
the CAN protocol, please refer to Bosch - CAN Specification for more details.
• Message filtering
• Message and status handling
• Fault confinement
• Error detection and signalling
• Message validation and acknowledgement
• Bus arbitration
• Message framing
• Transfer rate and timing
Supports CAN 2.0A and 2.0B protocol specifications
1 Mb/s maximum bitrate
2 CAN channels
16 Message Objects per CAN channel
1 identifier (11 or 29 bits), 1 identifier mask and 8 bytes buffer per MOb
Single shot and automatic transmit/receive modes
Overrun mode
Loop-back mode for bit rate detection
Listen mode for bus monitoring
System sleep mode support with wake-up on bus activity
Programmable CAN clock source
