13.5
Table 13.4 lists the HCAN interrupt sources. These sources can be masked except the reset
processing interrupt by power-on reset (IRR0). Masking is implemented using the mailbox
interrupt mask register (MBIMR), interrupt mask register (IMR), and IRQ enable register (IER).
For details on the interrupt vector of each interrupt source, refer to section 5, Interrupt Controller.
