• Reset Sequence
Following sequence is an example to configure the HCAN2 after Hardware/Software Reset.
After reset, all the registers are initialized, therefore, the HCAN2 needs to be configured before
joining the CAN bus activity. Read the notes carefully.
HCAN2 Settings
Notes: 1. Software reset could be performed at any time by setting MCR0=1.
Set CANTCR and CANTCMR
(STD-ID, EXT-ID, DLC, RTR,
IDE, MBC, MBIMR, DART,
ATX, NMC, LAFM)
2. Mailboxes are comprised of RAMs. Therefore, initialize all the mailboxes first
3. If CANTXPR is not set, HCAN2 will receive the next incoming message. If
4. Timer can be started at any time after CANTCR is set.

Clear required CANIMR
Clear all Mailboxes*
even if some of them are not used.
CANTXPR is set, HCAN2 will start transmission of the message and will be
arbitrated by the CAN bus. If it loses the arbitration, it will become a receiver.
