7.3.3
The ICR1 is a 16-bit register that specifies the detection mode to external interrupt input pins,
IRQ0 to IRQ5 individually: rising edge, falling edge, or low level. This register, initialized to
H'4000 at power-on reset or manual reset, is not initialized in the standby mode.
Bit 15—Mask All Interrupts (MAI): Masks NMI interrupts in standby mode when set to 1. Also
selects whether or not all interrupt requests are masked when a low level is being input to the NMI
pin.
Bit 15: MAI

1
Bit 14—Interrupt Request Level Detect (IRQLVL): Selects whether the IRQ3 to IRQ0 pins are
used as four independent interrupt pins or as 15-level interrupt pins encoded as IRL3 to IRL0.
Bit 14: IRQLVL Description

Bit 13—BL Bit Mask (BLMSK): Specifies whether NMI interrupts are masked when the BL bit
of the SR register is 1.
