If the interrupt generate factor is changed, the IR bit in the interrupt control register for the changed interrupt
may inadvertently be set to “1” (interrupt requested). If you changed the interrupt generate factor for an
interrupt that needs to be used, be sure to clear the IR bit for that interrupt to “0” (interrupt not requested).
Changing the interrupt generate factor refered to here means any act of changing the source, polarity or timing
of the interrupt assigned to each software interrupt number. Therefore, if a mode change of any peripheral
function involves changing the generate factor, polarity or timing of an interrupt, be sure to clear the IR bit for
that interrupt to “0” (interrupt not requested) after making such changes. Refer to the description of each
peripheral function for details about the interrupts from peripheral functions.
Figure 24.3 shows the Procedure for Changing the Interrupt Generate Factor.

Either an “L” level of at least tW(INH) or an “H” level of at least tW(INL) width is necessary for the signal
input to pins INT0 through INT5 regardless of the CPU operation clock.
If the POL bit in the INT0IC to INT5IC registers or the IFSR7 to IFSR0 bits in the IFSR register are
changed, the IR bit may inadvertently set to “1” (interrupt requested). Be sure to clear the IR bit to “0”

Procedure for Changing the Interrupt Generate Factor
Change the interrupt generate factor (including a mode change of peripheral function)
1. The above settings must be executed individually. Do not execute two or more settings
2. Use the I flag for the INTi interrupt (i = 0 to 5).

maskable interrupts can all be disabled without causing a problem, use the I flag.
Otherwise, use the corresponding ILVL2 to ILVL0 bit for the interrupt whose interrupt
