Enumeration Type Documentation

§ ADCLPF3_Resolution_Bits

enum ADCLPF3_Resolution_Bits

Resolution of ADC-conversion.

This sets the resolution of the ADC conversion, and will affect how long a conversion takes.

Enumerator
ADCLPF3_RESOLUTION_12_BIT
ADCLPF3_RESOLUTION_10_BIT
ADCLPF3_RESOLUTION_8_BIT

§ ADCLPF3_Reference_Source

enum ADCLPF3_Reference_Source

Specifies the source of the ADC reference voltage.

The ADC reference voltage will determine the upper limit of the input voltage.

Note: The actual reference values are slightly different for each device and are higher than the values specified above. This gain is saved in the FCFG. The function ADC_convertToMicroVolts() must be used to derive actual voltage values. Do not attempt to compare raw values between devices or derive a voltage from them yourself. The results of doing so will only be approximately correct.

Warning: Refer to the datasheet to make sure the input voltage to the ADC never exceeds the specifies limits.

§ ADCLPF3_Clock_Divider

enum ADCLPF3_Clock_Divider

ADC clock-divider.

This sets the clock divider value for the ADC clock, derived from the SYSCLK
