WebInterrupt On Change (IOC) is a hardware feature in most PIC ® devices. It is available on select I/O pins. When the hardware senses a change in state, low to high or high to low, an interrupt will occur. The Interrupt Service Routine (ISR) will be run, implementing any custom code the designer has developed.

WebApr 20, 2016 · The way interrupts work: The code sets the "Global Interrupt Enable" bit; without it, no interrupts will occur. When something happens to cause an interrupt, a flag is set. When the interrupt flag is noticed, the "Global Interrupt Enable" bit is cleared. The appropriate ISR is run. The "Global Interrupt Enable" bit is re-set. WebThe Microchip PIC series of microcontrollers have several sources of hardware interrupts. These are RISC microcontrollers with 35 instructions. To configure interrupts or other hardware functions are setup by configuring various bits in selected registers, in particular here the INTCOM register.
