15.3.7
There are 12 HCAN interrupt sources, to which five independent interrupt vectors are assigned.
Table 15.5 lists the HCAN interrupt sources.
With the exception of the reset processing vector (IRR0), these sources can be masked. Masking is
implemented using the mailbox interrupt mask register (MBIMR) and interrupt mask register
(IMR).
