This register can only be written if the WPEN bit is cleared in
• USCHx: User Sequence Number x
The sequence number x (USCHx) can be programmed by the Channel number CHy where y is the value written in this
field. The allowed range is 0 up to 7. So it is only possible to use the sequencer from CH0 to CH7.
This register activates only if ADC_MR(USEQ) field is set to ‘1’.
Any USCHx field is taken into account only if ADC_CHSR(CHx) register field reads logical ‘1’ else any value written in
USCHx does not add the corresponding channel in the conversion sequence.
When configuring consecutive fields with the same value, the associated channel is sampled as many time as the number
of consecutive values, this part of the conversion sequence being triggered by a unique event.
Configuring the same value in different fields leads to multiple samples of the same channel during the conversion
sequence. This can be done consecutively, or not, according to user needs.
