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 CH11.
This register activates only if AFEC_MR.USEQ is set.
Any USCHx field is taken into account only if AFEC_CHSR.CHx is set, 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, depending on user requirements.
