The intelligent I/O interrupt is assigned to software interrupt numbers 44 to 48.
When using the intelligent I/O interrupt, set the IRLT bit in the IIOiIE register (i = 0 to 4) to "1" (interrupt
request for interrupt used).
Various interrupt requests cause the intelligent I/O interrupt to occur. When an interrupt request is gen-
erated with each intelligent I/O or CAN functions, the corresponding bit in the IIOiIR register is set to "1"
(interrupt requested). When the corresponding bit in the IIOiIE register is set to "1" (interrupt enabled),
the IR bit in the corresponding IIOiIC register is set to "1" (interrupt requested).
After the IR bit setting changes "0" to "1", the IR bit remains set to "1" when a bit in the IIOiIR register is
set to "1" by another interrupt request and the corresponding bit in the IIOiIE register is set to "1".
Bits in the IIOiIR register are not set to "0" automatically, even if an interrupt is acknowledged. Set each
bit to "0" by program. If these bit settings are left "1", all generated interrupt requests are ignored.
Figure 10.13 shows a block diagram of the intelligent I/O interrupt. Figure 10.14 shows the IIOiIR
register. Figure 10.15 shows the IIOiIE register.
