CAN1 Wake-up
To configure for intelligent I/O interrupts, use IIOiIE register (i = 0 to 11), IIOiIR register, and IIOiIC (CANjIC (j =
0 to 5)) register.
Table 11.7 lists registers used for CAN interrupts, UART5 and UART6 transmit/receive interrupts, and INT6 to
INT8 interrupts. Figure 11.20 shows an interrupt request bit timing with multiple interrupt sources. Figure 11.21
shows an interrupt routine example.
CAN Interrupt
1. Only CAN00 to CAN02 interrupts can be used in M32C/87A. No CAN interrupt is provided in M32C/87B.
2. The IIO9IC register and the CAN0IC register share the same address. So do the IIO10IC register and CAN1IC
register, the IIO11IC register and the CAN2IC register, the IIO0IC register and the CAN3IC register, the IIO1IC
register and the CAN4IC register, and the IIO5IC register and the CAN5IC register.

IRLT bit
Set to 1 to use interrupt requests from individual peripheral functions for interrupts. Set to 0 to use them for
DMA or DMACII trigger sources.
Interrupt enable bit
Set the interrupt enable bit corresponding to the interrupt to be used, to 1 (interrupt enabled) after setting
the IRLT bit.
Interrupt request flag
The interrupt request flag becomes 1 (interrupt requested) when an interrupt request is generated. This flag
does not automatically become 0 when the interrupt request is acknowledged. Use AND or BCLR
instruction to set it to 0 (interrupt not requested) in the interrupt routine. If any of these flags remains 1, the
IR bit in the IIOiIC (CANjIC) register does not become 1 when an interrupt request is generated in the same
register. (Interrupt does not occur.)
If an interrupt request is generated while writing a 0 to the corresponding interrupt flag, the flag may not be
cleared to 0. In this case, keep writing a 0 until 0 is read.
IR bit
The IR bit in the IIOiIC register becomes 1 (interrupt requested), if all the enabled request flags in the
corresponding IIOiIR register are set to 0, and an interrupt request corresponding to one of these flags is
generated. The IR bit automatically becomes 0 when the interrupt is acknowledged.
