Each processor defines its own set of instructions and conventions to work with interrupts; however, all of them use the same general approach while dealing with interrupts: Interrupts are identified by numbers, starting with 0.The interrupt service routine should only execute the critical code; the rest of the task can be relegated to the main process by setting a flag variable. Note that since flags generally take binary values (0 or 1), these should be declared in bitwise memory wherever possible (like in 8051). frient air quality sensor Processing an interrupt requires transferring control to the appropriate service routine. This transfer is usually performed in several steps:.Nov 26, 2021 · Step 3 − Once the interrupt service routine is completed the address on the process stack is popped and placed back in the program counter. Step 4 − Now, it executes the resume for (i+1)th line. Multiple interrupts. Multiple interrupt is an interrupt event which can occur while the processor is handling a previous interrupt. The interrupt service routine counted the interrupts and flagged up when the data for chosen number of 𝐹𝑥 pulses N were fully collected in the memory buffer. The indi- vidual half-period counts were then averaged. 100 ms delay was actioned before starting the following measurement. 3. Experimental Results architecture guild meeting
