WebJan 17, 2024 · Popping the contents of the stack back into the register is the opposite function of pushing. When the POP instruction is executed, the SP is incremented by one and the top location of the stack is copied back to the register. This means that the stack is LIFO ( Last In First Out). To retrieve back the data from the stack, we use POP instruction. WebThe video explains the PUSH and POP opcodes of 8051 with the help of a small code which swaps the contents of two registers.
