Table 18-1 presents an overview of the CAN Controller functions.
Table 18-1:
Overview of Functions
Function
Details
Protocol
CAN protocol ISO 11898 (standard and extended frame transmission/reception)
Baud rate
Maximum 1 Mbps (CAN clock input
≥
8 MHz)
Data storage
Storing messages in the CAN RAM
Number of messages
•
32 message buffers per channel
•
Each message buffer can be set to be either a transmit message buffer or a
receive message buffer.
Message reception
•
Unique ID can be set to each message buffer.
•
Mask setting of four patterns is possible for each channel.
•
A receive completion interrupt is generated each time a message is received
and stored in a message buffer.
•
Two or more receive message buffers can be used as a FIFO receive buffer
(multi-buffer receive block function).
•
Receive history list function
Message transmission
•
Unique ID can be set to each message buffer.
•
Transmit completion interrupt for each message buffer
•
Message buffer number 0 to 7 specified as the transmit message buffer can be
set for automatic block transfer. Message transmission interval is programmable
(automatic block transmission function (hereafter referred to as “ABT”)).
•
Transmission history list function
Remote frame processing
Remote frame processing by transmit message buffer
Time stamp function
•
The time stamp function can be set for a message reception when a 16-bit timer
is used in combination.
•
Time stamp capture trigger can be selected (SOF or EOF in a CAN message
frame can be detected.).
•
The time stamp function can be set for a transmit message.
Diagnostic function
•
Readable error counters
•
“Valid protocol operation flag” for verification of bus connections
•
Receive-only mode
•
Single-shot mode
•
CAN protocol error type decoding
•
Self-test mode
Release from bus-off state
•
Forced release from bus-off (by ignoring timing constraint) possible by software.
•
No automatic release from bus-off (software must re-enable).
Power save mode
•
CAN Sleep mode (can be woken up by CAN bus)
•
CAN Stop mode (cannot be woken up by CAN bus)
