35.3.4
The IR bit in the interrupt control register may be set to 1 (interrupt requested) when the interrupt source
changes. To use an interrupt, set the IR bit to 0 (no interrupt requested) after changing interrupt sources.
Changing interrupt sources as referred to here includes all factors that change the source, polarity, or timing of
the interrupt assigned to a software interrupt number. Therefore, if a mode change of a peripheral function
involves the source, polarity, or timing of an interrupt, set the IR bit to 0 (no interrupt requested) after making
these changes. Refer to the descriptions of the individual peripheral functions for related interrupts.
Figure 35.1 shows a Procedure Example for Changing Interrupt Sources.
IR bit: Bit in the interrupt control register bit for the interrupt whose source is to be changed
Notes:
Changing Interrupt Sources
1. The above settings must be executed individually. Do not execute two or more settings
2. To prevent interrupt requests from being generated, disable the peripheral function
3. Refer to 11.8.5 Rewriting Interrupt Control Register for the instructions to use and
Procedure Example for Changing Interrupt Sources
simultaneously (using one instruction).
before changing the interrupt source. In this case, use the I flag if all maskable
interrupts can be disabled.
If all maskable interrupts cannot be disabled, use bits ILVL0 to ILVL2 for the interrupt
whose source is to be changed.
