POP PSW Instruction

It is similar to  above pop  instruction but instead of normal  register  pairs it uses PSW  as its operand. Program status word  comprises of the contents  of the  accumulator  and flag  register. The instruction format is


Hence  this instruction copies the contents  of the two  locations of the stack into accumulator  and flag  register.

Caution: All flag  are  replaced by the byte copied  from the stack.
