7.3.3
ICR1 is a 16-bit register that specifies the detection mode for external interrupt input pins IRQ0 to
IRQ5 individually: rising edge, falling edge, or low level. This register is initialized to H'4000 by a
power-on reset or manual reset, but is not initialized in standby mode.
Bit 15—Mask All Interrupts (MAI): When set to 1, all interrupt requests are masked while a
low level is being input to the NMI pin. Masks NMI interrupts in standby mode.
Bit 14—Interrupt Request Level Detect (IRQLVL): Selects whether the IRQ3–IRQ0 pins are
used as four independent interrupt pins or as 15-level interrupt pins encoded as IRL3–IRL0.
Bit 13—BL Bit Mask (BLMSK): Specifies whether NMI interrupts are masked when the BL bit
in the SR register is 1.
