6. Interrupt Controller (INTC)
6.3.2
ICR2 is a 16-bit register that sets the edge detection mode of the external interrupt input pins IRQ0
to IRQ7. 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 7 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.
