Name of the register which stores the address of the next instruction to be executed in 8085 in microprocessor

Program counter (PC):

• The program counter acts as a pointer to the next instruction to be executed and always contains the 16-bit address of the memory location of the next instruction
• It is a 16-bit register as 8085 has 16 address lines
• The program counter is updated by the processor and points to the next instruction after the processor has fetched the complete instruction.

Stack Pointer:

• Stack Pointer is also a special purpose register that is used to point the location of the top of the stack.
• Since location is specified using 16 bits, the stack pointer is a 16-bit register.

Accumulator: An accumulator is a register in which intermediate, arithmetic and logic results are stored.
