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.
