WebMay 6, 2024 · Pin 2 is the pin that triggers INT0, the first of two external interrupts, so if the button is pushed, the interrupt should be triggered (and it actually is, when using the sketch instead of the assembly code). I am activating both ext. ints, but that doesn't really matter. WebAn interrupt is the automatic transfer of software execution in response to a hardware event that is asynchronous with the current software execution.This hardware event is called a trigger.The hardware event can either be a busy to ready transition in an external I/O device (like the UART input/output) or an internal event (like bus fault, memory fault, or a …

WebExternal Pin Interrupt. The external pin interrupt is triggered whenever there is a "change of state" on the RB0/INT (pin #6 on the PIC16F84A). The change of state means the pin went from high to low or low to high. To enable this interrupt, you have to set the INTE (bit 4, External Interrupt Enable) bit of the INTCON register.
