Texas Instruments Tiva TM4C123GH6PM User Manual

Analog to Digital Converter (ADC)
Returns:
Returns zero if there was not an underflow, and non-zero if there was.
5.2.1.26 ROM_ADCSequenceUnderflowClear
Clears the underflow condition on a sample sequence.
Prototype:
void
ROM_ADCSequenceUnderflowClear(uint32_t ui32Base,
uint32_t ui32SequenceNum)
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_ADCSequenceUnderflowClear is a function pointer located at ROM_ADCTABLE[12].
Parameters:
ui32Base is the base address of the ADC module.
ui32SequenceNum is the sample sequence number.
Description:
This will clear an underflow condition on one of the sample sequences. The underflow condition
must be cleared in order to detect a subsequent underflow condition (it otherwise causes no
harm).
Returns:
None.
