Working Principles

The PIC16F886-I/SP operates based on the Von Neumann architecture, where program instructions and data are stored in separate memory spaces. The microcontroller fetches instructions from program memory, executes them using the central processing unit (CPU), and interacts with peripherals and external devices through input/output pins.

Upon power-up or reset, the microcontroller initializes its internal registers and begins executing the code stored in program memory. It can respond to external events through interrupts, perform calculations, control I/O operations, and communicate with other devices as per the programmed instructions.
