internal clock
In single channel input mode, with CS low and WR low, data is written into the ADC. The sampling begins at the falling edge of CSTART, and
conversion begins at the rising edge of CSTART. The internal clock turns on at the rising edge of CSTART. The internal clock is disabled after
each conversion.
