BIT             BIT Test bits in memory with accumulator              BIT

  Operation:  A /\ M -> Z, M7 -> N, M6 -> V                 N V - B D I Z C
                                                            M7M6. . . . / .
  Bit 6 and 7 are transferred to the status register.
  If the result of A /\ M is zero then Z = 1, otherwise Z=0.
