Interrupt Control Register 1 (ICR1)
ICR1 is a 16-bit register that specifies the detection mode for external interrupt input pins IRQ7 to
IRQ0 individually: low level, falling edge, rising edge, or both edges. ICR1 is initialized by a
power-on reset.

IRQ Sense Select
These bits select whether interrupt signals
corresponding to pins IRQ7 to IRQ0 are detected by a
low level, falling edge, rising edge, or both edges.
00: Interrupt request is detected on low level of IRQn
input
01: Interrupt request is detected on falling edge of IRQn
input
10: Interrupt request is detected on rising edge of IRQn
input
11: Interrupt request is detected on both edges of IRQn
input
