21.8.4 Transition from initialization mode to operation mode
Cautions 1. When a message is received, reception filtering is performed in accordance with the ID and
The CAN module can be switched to the following operation modes.
• Normal operation mode
• Normal operation mode with ABT
• Receive-only mode
• Single-shot mode
• Self-test mode
Figure 21-27. Setting Transmission Request (TRQ) to Transmit Message Buffer After Redefinition
2. When a message is transmitted, the transmission priority is checked in accordance with the
mask set to each receive message buffer. If the procedure in Figure 21-39 is not observed,
the contents of the message buffer after it has been redefined may contradict the result of
reception (result of reception filtering). If this happens, check that the ID and IDE received
first and stored in the message buffer following redefinition are those stored after the
message buffer has been redefined. If no ID and IDE are stored after redefinition, redefine the
message buffer again.
ID, IDE, and RTR bits set to each transmit message buffer to which a transmission request
was set. The transmit message buffer having the highest priority is selected for transmission.
If the procedure in Figure 21-27 is not observed, a message with an ID not having the highest
priority may be transmitted after redefinition.
Wait for 1 bit of CAN data.
