Analog Input ADC Settings
Reference Voltage – Gives user the ability to select the voltage
reference that will be used for the conversion. Options consist of the
AVDD_SOC supply voltage, the internal 1.25v reference, a voltage
applied to analog input pin 7 (P0_7), or the differential voltage
applied between analog input pins 6 and 7 (P0_6 and P0_7).
Conversion Resolution - Gives user the ability to select the resolution
of the conversion. Options consist of 8, 10, 12 or 14 bits of
resolution, and the conversion takes longer as the resolution of the
conversion increases.
Readings To Average – Gives user the ability to select the number of
ADC converter readings to average before returning a result.
Options consist of 1, 2, or 4 readings to average.
