can be requested, and if the mailbox empty interrupt (IRR8) is enabled for the bits (MBIMR1 to
MBIMR15) corresponding to the mailbox interrupt mask register (MBIMR) and interrupt mask
register (IMR), interrupts may be sent to the CPU.
However, a transmit wait message cannot be canceled at the following times:
• During internal arbitration or CAN bus arbitration
• During data frame or remote frame transmission
Figure 15.10 shows a flowchart for transmit message cancellation.
