  Tests specified bits of an operand and sets the flags for a subsequent
  conditional jump or set instruction. One of the operands contains the
  value to be tested. The other contains a bit mask indicating the bits
  to be tested. TEST works by doing a logical bitwise AND on the
  source and destination operands. The flags are modified according to
  the result, but the destination operand is not changed. This instruc-
  tion is the same as the AND instruction, except that the result is
  not stored.
