## Timing

It is up to you to respect call timing of the chip. (todo add misc method to aid in calculation)

## Resets

Any events that cause unexpected reset of the calibration register should be validate on the caller side.

## Power-down and Disabled Profiles

The default profile (32V /8 12bit 12bit continuous both) is reset when calling the shorthand **powerdown()** and **disableADC()** per spec, with the exception of using the 1sample version of the eum over the 12bit (useful in diagnostics).
