CMP

  Opcode Operand Description CMP R M Compare register or memory with accumulator     —    The   contents   of   the   operand   (register   or   memory)   are  compared  with the  contents  of the   accumulator.   —    Both  contents  are  preserved   . —    The   result   of   the   comparison   is   shown   by   setting   the  flags  of the PSW as   follows:   —    if (A) < (reg/mem): carry  flag  is   set —    if (A) = (reg/mem):  zero  flag  is   set —    if (A) > (reg/mem): carry and  zero  flags  are   reset. —    Example:  CMP B or CMP   M
