Interrupt Control Register (ICR)
ICR is a 16-bit register that sets the input signal detection mode of external interrupt input pin
NMI and indicates the input signal level at the NMI pin. It can also specify IRQ or IRL mode by
means of the External Interrupt Vector Mode Select bit. The IRQ/IRL interrupt vector number can
be selected for setting in accordance with either auto vector mode or external vector mode by
means of the Interrupt Vector Mode Select bit. ICR is initialized to H'8000 or H'0000 by a reset. It
is not initialized in standby mode.

Bit 15—NMI Input Level (NMIL): Sets the level of the signal input at the NMI pin. This bit can
be read to determine the NMI pin level. This bit cannot be modified.
Bit 15: NMIL
Description
0
NMI input level is low
1
NMI input level is high
Bits 14 to 9—Reserved: These bits are always read as 0. The write value should always be 0.
Bit 8—NMI Edge Select (NMIE): Selects whether the falling or rising edge of the interrupt
request signal to the NMI pin is detected.
Bit 8: NMIE
Description
0
Interrupt request is detected on falling edge of NMI input (Initial value)
1
Interrupt request is detected on rising edge of NMI input
Bits 7 to 2—Reserved: These bits are always read as 0. The write value should always be 0.
