Working Principle

The PIC16F18455T-I/SS works in a user-programmed environment. The user programs the microcontroller by writing code in the C programming language, which is then compiled into machine code. This machine code is fetched from Flash memory, decoded, and executed by the microcontroller\'s central processing unit (CPU). The CPU of the microcontroller communicates with other components on the board, like memory and peripherals, using a variety of buses.

The peripheral devices communicate with the CPU using interrupts, which are signals generated by the peripheral when it needs attention. The CPU responds to the interrupt by suspending the current process and executing the code associated with the peripheral. This process is known as an interrupt service routine. The peripheral device will then send the necessary data to the CPU and wait for the CPU to respond and pull the data before executing its own code.

The CPU will also execute branch instructions to jump to different parts of the program code in response to certain conditions. These conditions can be a certain input from a peripheral, a timer count, or a jump instruction issued by a higher-level program. The branch instruction is sent to the CPU where it is decoded and executed. The branch instruction then causes the program to jump to the specified address and execution then resumes from the specified address.
