Data and channel information are clocked in simultaneously and read out as two bytes using READ HIGH FIFO and READ LOW FIFO lines. In the event of bus contention, resistors limit peak output current. If both FIFOs are read completely or reset before a burst of conversions, the empty, half full, and full flags from only one FIFO need to be monitored. The retransmit inputs may also be tied together. Retransmit may be used to read data repeatedly, allowing a memory limited processor to perform trans- form and filtering functions that would otherwise be difficult.
