WebInterrupt routines were, by default, high priority. The 16- and 32-bit compilers have used the interrupt attribute to define interrupt functions. Migration to the CCI. For 8-bit compilers, … WebInterrupt Handling Mechanism. In the microcontroller we’re using (PIC16F877A), the interrupts are non-vectored in memory.

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. WebSearch... Loading... Login

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.
