NOTES:
1. This bit can only be reset by writing 0 (Do not write 1).
2. To rewrite the interrupt control registers, do so at a point that does not generate the interrupt request for that register.
For details, refer to 22. 4 Interrupts.
3. Use the IFSR2A register to select.

1. This bit can only be reset by writing 0 (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. For details, refer to 22.4 Interrupts.
3. If the IFSRi bit in the IFSR register (i = 0 to 5) is 1 (both edges), set the POL bit in the INTiIC register to 0
(falling edge).
4. Set the POL bit in register S3IC or S4IC to 0 (falling edge) when the IFSR6 bit in the IFSR register is set to 0
(SI/O3 selected) or IFSR7 bit in the IFSR register to 0 (SI/O4 selected), respectively.
Nothing is assigned. If necessary, set to 0.
