Command Register Descriptions
Perform Single Conversion
This command instructs the ADC to perform a single conversion.
Perform Continuous Conversions
This command instructs the ADC to perform continuous conversions.
Power Save/Run
If PS/R = 0, normal run mode is entered. If PS/R = 1, power save mode is entered.
Null
This command is used to clear the port flag in the continuous conversion mode when the port flag bit in the configuration register
is set to logic 1.
