Solutions

Expert Solution

Answer:

1) various registers in 8085:

  • Accumulator,
  • Temporary Registers(W and Z),
  • General Purpose Registers(B,C,D,E,H and L),
  • Instruction Register,
  • Stack Pointer,
  • Program Counter.

2)Various Flags Used in 8085:

  • Carry Flag,
  • Auxiliary Flag,
  • Sign Flag,
  • Zero Flag,
  • Parity Flag.

3)What is Stack Pointer:

  • Stack Pointer is a special purpose 16-bit register and it is used as a memory pointer.
  • It holds the address of the stack.
  • It is always Incremented or decremented by 2 while performing push and pop operations.

4)What is Program Counter:

  • It is also a special purpose 16-bit register.
  • It holds the address of the next instructin to be executed.
  • This register is used to sequence the execution of the instructions.
  • It is incremented by one to point to the next memory location.

​​​​​​​5)Which stack is used in 8085:

  • Last-In-First-Out(LIFO) Stack is used in 8085.
  • Which means The instruction that gets pushed last into the stack will be popped first from the stack.
