NOTES:
1. Only "0" can be written to the IR bit. (Do not write "1").
2. To rewrite the interrupt control register, do so at a point that does not generate the interrupt request for that register.
3. If the INTOPL bit in the INTEN register is set to “1” (both edges), set the POL bit to "0 " (selecting falling edge).
4. The IR bit may be set to “1” (interrupt requested) when the POL bit is rewritten. Refer to the paragraph 19.2.5

Refer to the paragraph 19.2.6 “Changing Interrupt Control Registers”.
