6.3.2
ICR2 is a 16-bit register that sets the edge detection mode of the external interrupt input pins IRQ0
to IRQ3. ICR2 is, however, valid only when IRQ interrupt request detection mode is set to the
edge detection mode by the sense select bits of IRQ0 to IRQ 3 in Interrupt control register 1
(ICR1). If the IRQ interrupt request detection mode has been set to low level detection mode, the
setting of ICR2 is ignored.

Description
IRQ2 Sense Select
This bit sets the IRQ2 interrupt request detection
mode.
0: Interrupt request is detected on low level of IRQ2
1: Interrupt request is detected on edge of IRQ2 input
IRQ3 Sense Select
This bit sets the IRQ3 interrupt request detection
mode.
0: Interrupt request is detected on low level of IRQ3
1: Interrupt request is detected on edge of IRQ3 input
Reserved
These bits are always read as 0. The write value
should always be 0.

This bit sets the IRQ0 interrupt request edge
detection mode.
