15.8.11 HCAN Transmit Procedure
When transmission is set while the bus is in the idle state, if the next transmission is set or the set
transmission is canceled under the following conditions within 50 μs, the transmit message ID of
being set may be damaged.
Make whichever setting shown below to avoid the message IDs from being damaged.
• Set transmission in one TXPR. After transmission of all transmit messages is completed, set
• Make the transmission setting according to the priority of transmit messages.
• Set the interval to be 50 μs or longer between TXPR and another TXPR or between TXPR and
Table 15.5 Interval Limitation between TXPR and TXPR or between TXPR and TXCR
15.8.12 Note on Releasing the HCAN Reset or HCAN Sleep
Before releasing the HCAN reset or HCAN sleep (MCR0 = 0 or MCR5 = 0), confirm that the
GSR3 bit (the reset status bit) is set to 1.
15.8.13 Note on Accessing Mailbox during the HCAN Sleep
Do not access the mailbox during the HCAN sleep. If accessed, the CPU might halt. Accessing
registers during the HCAN sleep does not cause the CPU halt, nor does accessing the mailbox in
other than the HCAN sleep mode.
