Analog to Digital Converter (ADC)
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_ADCIntClear is a function pointer located at ROM_ADCTABLE[4].
Parameters:
ui32Base is the base address of the ADC module.
ui32SequenceNum is the sample sequence number.
Description:
The specified sample sequence interrupt is cleared, so that it no longer asserts. This must be
done in the interrupt handler to keep it from being called again immediately upon exit.
Note:
Because there is a write buffer in the Cortex-M4 processor, it may take several clock cycles
before the interrupt source is actually cleared. Therefore, it is recommended that the interrupt
source be cleared early in the interrupt handler (as opposed to the very last action) to avoid
returning from the interrupt handler before the interrupt source is actually cleared. Failure to
do so may result in the interrupt handler being immediately reentered (because the interrupt
controller still sees the interrupt source asserted).
Returns:
None.
5.2.1.10 ROM_ADCIntDisable
Disables a sample sequence interrupt.
Prototype:
void
ROM_ADCIntDisable(uint32_t ui32Base,
uint32_t ui32SequenceNum)
ROM Location:
