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 11. So it is only possible to use the sequencer from CH0 to
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.
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.
