If edge interrupt is set, the ISR will only get fired on falling/rising edge of a pulse. While if level sensitive interrupt (as you say) is set the ISR will get fired everytime there is a low-level/high-level signal on the corresponding pin.

NettetChoosing the edge at which an interrupt occurs is done be setting or clearing the INTEDG bit of the OPTION_REG register. We’ll set it so as to get an interrupt signal on every rising edge on the RB0 pin. 1 INTEDG = 1; // Interrupt Occurs On Every Rising Edge Step2 – Configure The RB0 Interrupt NettetStep1 – Select The IO pin and Edge.
