Analog to Digital Converter (ADC)
Prototype:
void
ROM_ADCComparatorRegionSet(uint32_t ui32Base,
uint32_t ui32Comp,
uint32_t ui32LowRef,
uint32_t ui32HighRef)
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_ADCComparatorRegionSet
is a function pointer located at
ROM_ADCTABLE[16]
.
Parameters:
ui32Base is the base address of the ADC module.
ui32Comp is the index of the comparator to configure.
ui32LowRef is the reference point for the low/mid band threshold.
ui32HighRef is the reference point for the mid/high band threshold.
Description:
The ADC digital comparator operation is based on three ADC value regions:
low-band is defined as any ADC value less than or equal to the ui32LowRef value.
mid-band is defined as any ADC value greater than the ui32LowRef value but less than
or equal to the ui32HighRef value.
high-band is defined as any ADC value greater than the ui32HighRef value.
Returns:
None.
5.2.1.7 ROM_ADCComparatorReset
Resets the current ADC digital comparator conditions.
Prototype:
void
ROM_ADCComparatorReset(uint32_t ui32Base,
uint32_t ui32Comp,
bool bTrigger,
bool bInterrupt)
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_ADCComparatorReset
is a function pointer located at
ROM_ADCTABLE[17]
.
Parameters:
ui32Base is the base address of the ADC module.
ui32Comp is the index of the comparator.
bTrigger
is the flag to indicate reset of Trigger conditions.
bInterrupt
is the flag to indicate reset of Interrupt conditions.
