The listed Word Rates are for continuous conversion mode using a 4.9152 MHz clock. All word rates will
scale linearly with the clock frequency used. The very first conversion using continuous conversion mode
will last longer, as will conversions done with the single conversion mode. See the section on Performing
Conversions and Tables 1 and 2 for more details.

Select Bipolar mode.
Select Unipolar mode.
When set, this bit activates a 300 nA current source on the input channel (AIN+) selected by the channel
select bits. Note that the 300nA current source is rated at 25°C. This feature is particularly useful in ther-
mocouple applications when the user wants to drive a suspected open thermocouple lead to a supply rail.
Normal mode.
Activate current source.
Must always be logic 0. Reserved for future upgrades.
