38.6.3 ADC Channel Sequence Register 1

Bits 0:3, 4:7, 8:11, 12:15, 16:19, 20:23, 24:27, 28:31 – USCHx User Sequence Number x

The allowed range is 0 to 15, thus only a CH0 to CH15 sequence can be used.

This register can be used only if ADC_MR.USEQ is set to ‘1’.

Any USCHx field is processed only if the bit CHx-1 in ADC_CHSR 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.

Example: For each trigger event, to obtain the “CH3 CH1 CH0 CH4 CH4” conversion sequence, use the following settings:

ADC_SEQR1.USCH1=3, ADC_CHSR.CH0=1

ADC_SEQR1.USCH2=1, ADC_CHSR.CH1=1

ADC_SEQR1.USCH3=0, ADC_CHSR.CH2=1

ADC_SEQR1.USCH4=4, ADC_CHSR.CH3=1

ADC_SEQR1.USCH5=4, ADC_CHSR.CH4=1
