(1) To calculate the time between conversion request and the availability of the conversion result, add the initialization time to the tmeasure as explained in Comparing Operating Modes Table. For continuous conversion, the initialization time is applicable only for the first conversion.
(2) Add 25 µs for each additional channel enabled for conversion with CONV_AVG =000.
(3) For conversion with CONV_AVG =101, each axis data is collected 32 times. If an additional channel is enabled with CONV_AVG =101, add 32×25µs = 800µs to the tmeasure to calculate the conversion time for two axes.
