- Some ADCs clock out the previous conversion if you talk to it a little early (before the conversion is complete).... this is ideal!
- Some ADCs clock out 0xFF's when you talk to them a little early.... this is ok since you can just throw away that conversion and you've only lost one data point.
- And some ADCs go into "Self Calibration Mode" and are dead to the world for 100ms if you talk to them too early..... this sucks and is a very poor design in my point of view.

The battle of two Clocks.... Independent and Stubborn!
Working for a Weighscale company has given me the opportunity to play around with many different 20/24-bit Delta-Sigma Analog-to-Digital Converters (ADCs) and they all behave a little differently when you clock the data out.
