6.3.4
ICR2 is a 16-bit register that specifies the detection mode for external interrupt input pins PINT7
to PINT0 individually: low level or high level. ICR2 is initialized by a power-on reset or in deep
standby mode.
[Legend]
n = 7 to 0
6.3.5
IRQRR is a 16-bit register that indicates interrupt requests from external input pins IRQ7 to IRQ0.
If edge detection is set for the IRQ7 to IRQ0 interrupts, writing 0 to the IRQ7F to IRQ0F bits after
reading IRQ7F to IRQ0F = 1 cancels the retained interrupts.
IRQRR is initialized by a power-on reset or in deep standby mode.

Description
Reserved
These bits are always read as 0. The write value
should always be 0.
PINT Sense Select
These bits select whether interrupt signals
corresponding to pins PINT7 to PINT0 are detected by
a low level or high level.
0: Interrupt request is detected on low level of PINTn
1: Interrupt request is detected on high level of PINTn
