Description
3 periods of ADCClock
5 periods of ADCClock
9 periods of ADCClock
17 periods of ADCClock
Description
Normal Mode: The controller converts channels in a simple numeric order.
User Sequence Mode: The sequence respects what is defined in ADC_SEQR1 and ADC_SEQR2
registers.
Description
No analog change on channel switching: DIFF0, GAIN0 and OFF0 are used for all channels
Allows different analog settings for each channel. See ADC_CGR and ADC_COR Registers
