when read are indeterminate.

0: Interrupt not requested
1: Interrupt requested
0 : Selects falling edge (Notes 3, 5)
1 : Selects rising edge
Must always be set to “0”
ILVL1
ILVL2
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: During memory expansion and microprocessor modes, set the INT3IC register’s ILVL2 to ILVL0 bits to ‘0002’
(interrupt disabled).
Note 5: 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.
