Analog to Digital Converter (ADC)
Returns:
None.
5.2.1.21 ROM_ADCSequenceEnable
Enables a sample sequence.
Prototype:
void
ROM_ADCSequenceEnable(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_ADCSequenceEnable is a function pointer located at ROM_ADCTABLE[5].
Parameters:
ui32Base is the base address of the ADC module.
ui32SequenceNum is the sample sequence number.
Description:
Allows the specified sample sequence to be captured when its trigger is detected. A sample
sequence must be configured before it is enabled.
Returns:
None.
5.2.1.22 ROM_ADCSequenceOverflow
Determines if a sample sequence overflow occurred.
Prototype:
int32_t
ROM_ADCSequenceOverflow(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_ADCSequenceOverflow is a function pointer located at ROM_ADCTABLE[9].
Parameters:
ui32Base is the base address of the ADC module.
ui32SequenceNum is the sample sequence number.
Description:
This determines if a sample sequence overflow has occurred. This will happen if the captured
samples are not read from the FIFO before the next trigger occurs.
Returns:
Returns zero if there was not an overflow, and non-zero if there was.
