Data Mode Select Input
Chip-Select Input. Must be low to select device.
Byte Address/Short-Cycle Input. When starting a conversion, controls number of bits converted (low = 12
bits, high = 8 bits). When reading data, if 12/8 = low, enables low byte (A0 = high) or high byte (A0 = low).
Read/Convert Input. When high, the device will be in the data-read mode. When low, the device will
be in the conversion start mode.
