0
Only 0 can be w ritten to the IR bit. (Do not w rite 1.)
Rew rite the interrupt control register w hen the interrupt request w hich is applicable for the register is not generated.
Refer to 12.6.5 Changing Interrupt Control Register Contents.
If the INTiPL 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 12.6.4 Changing Interrupt
Sources.
