42.8.3 ADC Channel Sequence 1 Register
Name:
ADC_SEQR1
Address:
0xF804C008
Access:
Read-write
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 CH11

.
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.
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.
