Note 6:
For partial power-down and full power-down modes, external clock mode was used for a burst of continuous samples.
Partial power-down or full power-down modes were entered thereafter. By using this method, the conversion rate was found
by averaging the number of conversions over the time starting from the first conversion to the end of the partial power-down
or full power-down modes.
