In this section, we did a list of hardware devices called programmer. These devices are used to write in the microcontroller memory the machine language code. For a precise control, the microcontrollers may operate under instructions. These instructions are commands written for microcontroller and divided into various categories including arithmetic, logic, data transfer, Boolean variables, and machine control instructions.

Register provides a fast way to collect and store data using microcontrollers and processors. If we want to manipulate data with a controller or processor by performing tasks like addition, subtraction, and so on, we cannot do that directly in the memory, in order to perform these tasks we need registers to process and store the data.

Microcontrollers contain several types of registers that can be classified according to their content or instructions that operate on them. The microcontroller contains mainly two types of registers:.

The microcontroller consists of bytes of RAM memory, which is divided into two ways, such as bytes for general purpose and bytes for special function registers SFR memory. In a stack pointer is 8 bits wide register to access stack. The stack is a section of RAM used by the CPU to store information temporarily information could be data or an address.

Generally, used bank1 of internal RAM as the stack so the default stack pointer is 07H. When Microcontroller is under sudden interrupt, it will call ISR Interrupt service routine that will store the address of current memory address and takes the control to new interrupt memory address. After the interrupt, the control will transfer back to its previous address.

Interrupt: An interrupt is a signal to the processor emitted by hardware or software indicating an event that needs immediate attention. An interrupt alerts the processor to a high-priority condition requiring the interruption of the current code the processor is executing.

The processor responds by suspending its current activities, saving its state, and executing a function called an interrupt handler or an interrupt service routine, ISR to deal with the event. This interruption is temporary, and, after the interrupt handler finishes, the processor resumes normal activities. There are two types of interrupts: hardware interrupts and software interrupts. Its architecture consists of following units.

Microcontroller has a 16 bit address bus for transferring the data. It is bi-directional as Microprocessor requires to send or receive data. The data bus also works as address bus when multiplexed with lower order address bus.

Control Bus: Control bus manages the information flow between components indicating whether the operation is a read or a write and ensuring that the operation happens at the right time. Trap interrupt has the highest priority. Binu , Aug 31, Downloads: Updated: Jun 25, Updated: Jun 25, Featured Zigbee based wireless weather monitoring system 1.
