start of conversion mechanism
There are two ways to convert data: hardware and software. In the hardware conversion mode the ADC begins
sampling at the falling edge of CSTART and begins conversion at the rising edge of CSTART. Software start
mode ADC samples for 6 clocks, then conversion occurs for ten clocks. The total sampling and conversion
process lasts only 16 clocks in this case. If RD is not detected during the next clock cycle, the ADC automatically
proceeds to a power-down state. Data is valid on the rising edge of INT in both conversion modes.
hardware CSTART conversion
external clock
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. At the end of conversion, EOC goes from low to high, telling
the host that conversion is ready to be read out. The external clock is active and is used as the reference at all
times. With this mode, it is required that CSTART is not applied at the rising edge of the clock (see Figure 4).
