Rewrite the Interrupt Control Register
Interrupt control register
(a) The interrupt control register for any interrupt should be modified in places where no requests for that interrupt
(b) To rewrite the interrupt control register for any interrupt after disabling that interrupt, be careful with the
(c) When using the I flag to disable an interrupt, refer to the sample program fragments shown below as you set
Examples 1 through 3 show how to prevent the I flag from being set to “1” (interrupts enabled) before the interrupt
control register is rewrited, owing to the effects of the internal bus and the instruction queue buffer.

may occur. Otherwise, disable the interrupt before rewriting the interrupt control register.
instruction to be used.
• Changing any bit other than the IR bit
• Changing the IR bit
the I flag. (Refer to (b) for details about rewrite the interrupt control registers in the sample program frag-
ments.)
Depending on the instruction used, the IR bit may not always be cleared to “0” (interrupt not requested).
Therefore, be sure to use the MOV instruction to clear the IR bit.
