The PUSHF and PUSHFD instructions have the same operation code and their Pop all 16-bit general-purpose registers (POPA) The POPA instruction is used to Previous: Load and Move Instructions · Next: Push Instructions The eight 16-bit general registers are popped by popa. However, the SP value is not This instruction pops the top 8 words off the stack into the 8 general purpose 16/32 bit registers. Registers are popped in the following order: (E)DI, POPA/POPAD - Pop All Registers onto Stack (80188+) Usage: POPA POPAD (386+) Modifies flags: None Pops the top 8 words off the stack into the 8 general Do watch video on PUSH and PUSHA data transfer instruction to understand these instructions.The POPA (pop all) and POPAD (pop all double) mnemonics reference the same opcode. The POPA instruction is intended for use when the operand-size attribute This instruction works similarly to popa, but pops the 32-bit general purpose registers off of the stack instead of their 16-bit counterparts. PUSHA pushes all 16-bit general-purpose registers onto the stack. This instruction is present on the 286 and later CPUs and is not available in the 8086/8088.
