    POPA pops the eight general registers from the stack. The value
    for the stack pointer is discarded instead of loaded into SP/ESP.
    POPA reverses the action of a previous PUSHA instruction.

    POPAD is the 32-bit form of POPA.


    Note
    Some assemblers support a POPA extension (POPAW) that forces 8
    16-bit word-style pop's regardless of the code segment's size
    attribute (80386+).
