Function
Don’t Care
External Interrupt 2
Enable bit if set
Interrupt Enable
If IT2=1, IE2 is set/cleared automatically by hardware when interrupt is detected/
serviced.
External Interrupt 2 is falling-edge/low-level triggered when this bit is cleared by
software.
External Interrupt 3
Enable bit if set
Interrupt Enable
If IT3=1, IE3 is set/cleared automatically by hardware when interrupt is detected/
serviced.
External Interrupt3 is falling-edge/low-level triggered when this bit is cleared by
software.
