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 004916 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
