23.3.4 CAN Bus Error Timing
The CAN0 wake-up interrupt and CAN0j interrupts (j=0 to 2) are provided as the CAN interrupt.

Figure 23.41 shows a block diagram of the CAN0j interrupts. The followings cause the CAN-associated
interrupt request to be generated.
The INTSEL bit in the C0CTLR1 register determines how an interrupt request is generated. When the
INTSEL bit is set to "0", one of the above CAN0 interrupt request source causes the CAN0j interrupts to
be generated by the OR circuit. When the INTSEL bit is set to "1", CAN0 transmission completed, CAN0
reception completed and CAN0 errors (CAN0 bus error detection, CAN0 module into error-passive state
and CAN0 module into bus-off state) cause the CAN0j interrupt corresponding to each source to be
generated.
- The CAN0 slot k (k=0 to 15) completes a transmission
- The CAN0 slot k completes a reception
- The CAN0 module detects a bus error
- The CAN0 module moves into an error-passive state
- The CAN0 module moves into a bus-off state
