After Reset
1. To set the INTiPL bit (i = 0 to 3) to 1 (both edges), set the POL bit in the INTiIC register to 0 (falling edge
2. The IR bit in the INTiIC register may be set to 1 (interrupt requested) if the INTEN register is rewritten. Refer to
After Reset
1. To set the INT4PL bit to 1 (both edges), set the POL bit in the INT4IC register to 0 (falling edge selected).
2. The IR bit in the INT4IC register may be set to 1 (interrupt requested) if the INTEN1 register is rewritten. Refer to
