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