0
Only “0” can be w ritten to the IR bit. (Do not w rite “1”.)
To rew rite the interrupt control register, rew rite it w hen the interrupt request w hich is applicable for its register is not
generated. Refer to 20.2.6 Changing Interrupt Control Registers.
If the INTOPL bit in the INTEN register is set to “1” (both edges), set the POL bit to “0” (selects falling edge).
The IR bit may be set to “1” (requests interrupt) w hen the POL bit is rew ritten. Refer to 20.2.5 Changing Interrupt
Factor.
