the mailbox empty interrupt bit (IMR8) in the interrupt mask register (IMR) are both
simultaneously set to enable interrupts, 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 15.9 shows a flowchart for transmit message cancellation.
