Mailbox Transmit/Receive Settings: HCAN0, 1 each have 16 mailboxes. Mailbox 0 is receive-
only, while mailboxes 1 to 15 can be set for transmission or reception. Mailboxes that can be set
for transmission or reception must be designated either for transmission use or for reception use
before communication begins. The Initial status of mailboxes 1 to 15 is for transmission (while
mailbox 0 is for reception only). Mailbox transmit/receive settings are not initialized by a software
reset.
• Setting for transmission
Transmit mailbox setting (mailboxes 1 to 15)
Clearing a corresponding mailbox in the mailbox configuration register (MBCR) to 0
designates the specified mailbox for transmission use. After a reset, mailboxes are initialized
for transmission use, so this setting is not necessary.
• Setting for reception
Transmit/receive mailbox setting (mailboxes 1 to 15)
