z
Bits 7:2 – Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always write these bits to 
zero when this register is written. These bits will always return zero when read.
z
Bit 1 – START: ADC Start Conversion
0: The ADC will not start a conversion.
1: The ADC will start a conversion. The bit is cleared by hardware when the conversion has started. Setting this bit 
when it is already set has no effect.
Writing this bit to zero will have no effect.
z
Bit 0 – FLUSH: ADC Conversion Flush
0: No flush action.
1: The ADC pipeline will be flushed. A flush will restart the ADC clock on the next peripheral clock edge, and all 
conversions in progress will be aborted and lost. This bit is cleared until the ADC has been flushed.
After the flush, the ADC will resume where it left off; i.e., if a conversion was pending, the ADC will start a new 
conversion.
Writing this bit to zero will have no effect.
