Nothing is assigned.
In an attempt to write to these bits, write “0.” The value, if read, turns out to
be indeterminate.
Interrupt priority level
select bit
Interrupt request bit
Polarity select bit
(Note 2)
Reserved bit
0: Interrupt not requested
1: Interrupt requested
0 : Selects falling edge
1 : Selects rising edge
Must always be set to “0”
ILVL1
ILVL2
Notes 1: This bit can only be accessed for reset (= 0), but cannot be accessed for set (= 1).
2: Bit 4 at address 0049 16 is invalid. Must always be set to “0.”
3: To rewrite the interrupt control register, do so at a point that does not generate the
interrupt register for that register. For details, see the precautions for interrupts.
