Page 660 of 1458
Mailbox transmit/receive settings should be made in advance. A total of 30 mailbox can be set
for transmission or reception (mailboxes 1 to 15 in HCAN0 and HCAN1). To set a mailbox for
transmission, clear the corresponding bit to 0 in the mailbox configuration register (MBCR).
Refer to Mailbox Transmit/Receive Settings in 16.3.2, Initialization after Hardware Reset, for
details.
As message control/data registers (MCx[x], MDx[x]) are configured in RAM, their initial
values after powering on are undefined, and so bit initialization is necessary. Write 0s or 1s to
the mailboxes. See Mailbox (Message Control/Data (MCx[x], MDx[x]) Initial Setting in
16.3.2, Initialization after a Hardware Reset, for details.
Set the transmission method for mailboxes designated for transmission. The following two
transmission methods can be used. Refer to Message Transmission Method Setting in 16.3.2,
Initialization after Hardware Reset, for details.
a. Transmission order determined by message identifier priority
b. Transmission order determined by mailbox number priority
