1. Do not generate a transmit request in bus monitoring mode.
1. Set the CiMDR register while the STATE_RESET bit in the CiSTR register is 1 (CAN module is in reset).
2. The value is obtained by setting the SLEEP bit in the CiSLPR register to 1 (sleep mode exited) after reset and supplying the
Normal operating mode: Normal transmit and receive operations are enabled.

to high level (“H”) in bus monitoring mode. The CAN module transmits neither ACK nor error frame.
Self-test mode: The CAN module connects the CANiOUT pin to the CANiIN pin internally. The CAN
module can communicate without additional device when using self-test mode and loop back mode. Output
signal from the CANiOUT pin is fixed to “H” in self-test mode while transmitting. Figure 23.20 shows an
image diagram in self-test mode.
clock to the CAN module.
The CAN module in bus monitoring mode considers dominant “L” is received regardless of whether the
actual ACK bit is dominant “L” or recessive “H”. Therefore, when a transmit operation is completed until
EOF, the CAN module determines a receive operation is successfully completed even if the ACK bit is
recessive “H”.
