Analog to Digital Converter (ADC)
Parameters:
ui32Base is the base address of the ADC module.
Description:
Returns the value of the ADC reference setting. The returned value is one of ADC_REF_INT
or ADC_REF_EXT_3V.
Returns:
The current setting of the ADC reference.
5.2.1.17 ROM_ADCReferenceSet
Selects the ADC reference.
Prototype:
void
ROM_ADCReferenceSet(uint32_t ui32Base,
uint32_t ui32Ref)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_ADCTABLE is an array of pointers located at ROM_APITABLE[5].
ROM_ADCReferenceSet is a function pointer located at ROM_ADCTABLE[22].
Parameters:
ui32Base is the base address of the ADC module.
ui32Ref is the reference to use.
Description:
The ADC reference is set as specified by ui32Ref . It must be one of ADC_REF_INT or
ADC_REF_EXT_3V, for internal or external reference. If ADC_REF_INT is chosen, then an
internal 3V reference is used and no external reference is needed. If ADC_REF_EXT_3V is
chosen, then a 3V reference must be supplied to the AVREF pin.
Returns:
None.
5.2.1.18 ROM_ADCSequenceConfigure
Configures the trigger source and priority of a sample sequence.
Prototype:
void
ROM_ADCSequenceConfigure(uint32_t ui32Base,
uint32_t ui32SequenceNum,
uint32_t ui32Trigger,
uint32_t ui32Priority)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_ADCTABLE is an array of pointers located at ROM_APITABLE[5].
ROM_ADCSequenceConfigure is a function pointer located at ROM_ADCTABLE[7].
