4. PARALLEL PORT
The DS21354/DS21554 are controlled through either a nonmultiplexed (MUX = 0) or a multiplexed
(MUX = 1) bus by an external microcontroller or microprocessor. The device can operate with either Intel
or Motorola bus timing configurations. If the BTS pin is tied low, Intel timing is selected; if tied high,
Motorola timing is selected. All Motorola bus signals are listed in parentheses (). See the timing diagrams
in Section
4.1.
