Active-Low Write Input. Drive WR low to write to the
ADC. Configuration registers are loaded on the rising
edge of WR.
Active-Low Chip-Select Input. Drive CS low when
reading from or writing to the ADC.
Active-Low Read Input. Drive RD low to read from the
ADC. Each rising edge of RD advances the channel
output on the data bus.
