Interrupt Control Register
b7 b6 b5 b4
NOTES:
1. This bit can only be reset by writing "0" (Do not write "1").
2. Rewrite the interrupt control register when the interrupt request related to the register is not generated. For
details, refer to 20.5 Interrupts.
3. Use the IFSR2A register to select.

NOTES:
1. This bit can only be reset by writing "0" (Do not write "1").
2. Rewrite the interrupt control register when the interrupt request related to the register is not generated. For
details, refer to 20.5 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 the S3IC or S4IC register 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 reister "0" (SI/O4 selected), respectively.
