Notes: The time quanta value for TSEG1 and TSEG2 is the TSEG value + 1.
* Only a value other than BRP[13:8] = B'000000 can be set.
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 bit to 0 in the mailbox configuration register (MBCR) designates the corresponding
mailbox for transmission use. After a reset, mailboxes are initialized for transmission use, so
this setting is not necessary.
