5.2.1 Function Documentation
5.2.1.1 ROM_ADCComparatorConfigure
Configures an ADC digital comparator.
Prototype:
void
ROM_ADCComparatorConfigure(uint32_t ui32Base,
uint32_t ui32Comp,
uint32_t ui32Config)
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_ADCComparatorConfigure is a function pointer located at ROM_ADCTABLE[15].
Parameters:
ui32Base is the base address of the ADC module.
ui32Comp is the index of the comparator to configure.
ui32Config is the configuration of the comparator.
Description:
This function will configure a comparator. The ui32Config parameter is the result of a logical
OR operation between the ADC_COMP_TRIG_xxx, and ADC_COMP_INT_xxx values.
The ADC_COMP_TRIG_xxx term can take on the following values:
ADC_COMP_TRIG_NONE to never trigger PWM fault condition.
ADC_COMP_TRIG_LOW_ALWAYS to always trigger PWM fault condition when ADC out-
put is in the low-band.
ADC_COMP_TRIG_LOW_ONCE to trigger PWM fault condition once when ADC output
transitions into the low-band.
