WebDec 15, 2024 · Multiple interrupts are usually combined into 1 active-low interrupt pin using a wire-ANDing, wire-ORing if active high (less common). That technique was/is used in thousands of designs. Interrupt requests may be open-drain, ready for tying to a pull-up resistor, or made open-drain with an 0.3V signal diode, or go into a wide AND gate. WebUSING A PORTB INPUT FOR AN EXTERNAL INTERRUPT The interrupt source(s) cannot simply be directly connected to the PORTB pins, and expect an interrupt to occur the same as on the interrupt (INT) pin.
