MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The register which stores the address of the next instruction is called the program counter. Usually after each instruction is executed, the program counter increases by one (hence the use of the word counter) so that it contains the address of the next instruction.

Detailed explanation-2: -A program counter (PC) is a CPU register in the computer processor which has the address of the next instruction to be executed from memory.

Detailed explanation-3: -A program counter is used to keep track of the execution of the program. It contains the memory address of the next instruction to be fetched. The program counter contains the address of the next instruction to be fetched from the main memory when the previous instruction has been successfully completed.

Detailed explanation-4: -A program counter is a register in a computer processor that contains the address (location) of the instruction being executed at the current time. As each instruction gets fetched, the program counter increases its stored value by 1.

Detailed explanation-5: -program counter-holds the memory address of the next instruction to be fetched from main memory. memory address register (MAR)-holds the address of the current instruction that is to be fetched from memory, or the address in memory to which data is to be transferred.
