Bit 8—NMI Edge Select (NMIE): Specifies whether the falling or rising edge of the interrupt
request signal to the NMI pin is detected.

Bit 7—IRL Pin Mode (IRLM): Specifies whether pins
encoded interrupt requests or as four independent interrupt requests.

Bits 13 to 10 and 6 to 0—Reserved: These bits are always read as 0, and should only be written
with 0.

Interrupt Priority Level Settting Register 00 (INTPRI00)
The interrupt priority level setting register (INTPRI00) sets the order of priority (levels 15 to 0) of
the internal peripheral module interrupts. The INTPRI00 register is a 32-bit read/write register. It
is initialized to H'00000000 at a reset. It is not initialized in standby mode.
