PUSH PSW Instruction

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

PUSHPSW

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

The contents of accumulator flag register remain unchanged .
