WebAn interrupt is a signal sent to the processor that interrupts the current process. It may be generated by a hardware device or a software program. A hardware interrupt is often created by an input device such as a mouse or keyboard. An interrupt is sent to the processor as an interrupt request, or IRQ. WebThe 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. sphere hazyWeb2) Set submodule 0 to compare, arm interrupt . 3) Set the TAxCCR0 to the interrupt period minus 1 . 4) Set the priority in the correct NVIC Priority register 5) Enable the interrupt in the NVIC Interrupt Enable register 6) Reset the timer and start it in up mode 7) Enable interrupts (in the main program after all devices initialized) sphere hanging light
