No functions are assigned.
When writing to these bits, write “0”. The values in these bits
when read are indeterminate.
Note 1: This bit can only be reset by writing "0" (Do not write "1").
Note 2: To rewrite the interrupt control registers, do so at a point that does not generate the interrupt request for that
register. For details, see the precautions for interrupts.
Note 3: Use the IFSR2A register to select.

when read are indeterminate.
Note 1: This bit can only be reset by writing "0" (Do not write "1").
Note 2: To rewrite the interrupt control register, do so at a point that does not generate the interrupt request for that
register. For details, see the precautions for interrupts.
Note 3: If the IFSR register’s IFSRi bit (i = 0 to 5) is "1" (both edges), set the INTiIC register’s POL bit to "0 "(falling
edge).
Note 4: Set the S3IC or S4IC register’s POL bit to "0" (falling edge) when the IFSR register’s IFSR6 bit = 0 (SI/O3
selected) or IFSR7 bit = 0 (SI/O4 selected), respectively
.
