Microcontroller requires a program which is a collection of instructions. This program tells microcontroller to do specific tasks. These programs require a memory on which these can be saved and read by Microcontroller to perform specific operations of a particular task.
The memory which is used to store the program of the microcontroller is known as code memory or Program memory of applications. It is known as ROM memory of microcontroller also requires a memory to store data or operands temporarily of the micro controller.
The data memory of the is used to store data temporarily for operation is known RAM memory. Basically Bus is a collection of wires which work as a communication channel or medium for transfer of Data.
These buses consists of 8, 16 or more wires of the microcontroller. Thus, these can carry 8 bits,16 bits simultaneously. Hire two types of buses that are shown in below.
Address Bus : Microcontroller has a 16 bit address bus for transferring the data. It is used to address memory locations and to transfer the address from CPU to Memory of the microcontroller. Microcontroller also required memory for storage of data and operands for the short duration.
Bus : Bus is a group of wires which uses as a communication canal or acts as means of data transfer. The different bus configuration includes 8, 16 or more cables. Therefore, a bus can bear 8 bits, 16 bits all together. Oscillator : As the microcontroller is digital circuit therefore it needs timer for their operation. To perform timer operation inside microcontroller it required externally connected or on-chip oscillator. Microcontroller is used inside an embedded system for managing the function of devices.
Therefore, uses the two 16 bit counters and timers. For the operation of this timers and counters the oscillator is used inside microcontroller. JavaTpoint offers too many high quality services.
