Notes
1.
A wake-up interrupt is also generated, if the CPU tries to set the sleep bit while the CAN controller is involved in bus
activities or a CAN interrupt is pending.
The behaviour of this bit is equivalent to that of the receive buffer status bit with the exception, that RI depends on
the corresponding interrupt enable bit (RIE). So the receive interrupt bit is not cleared upon a read access to the
interrupt register. Giving the command ‘release receive buffer’ will clear RI temporarily. If there is another message
available within the FIFO after the release command, RI is set again. Otherwise RI remains cleared.

The register allows to enable different types of interrupt sources which are indicated to the CPU.
The interrupt enable register appears to the CPU as a read/write memory.
