66.6.16.1 Classic ADC Channels Only (Touchscreen Disabled)

When no touchscreen conversion is required (i.e., ADC_TSMR.TSMODE = 0), the data structure within the buffer is defined by ADC_MR, ADC_CHSR, ADC_SEQR1. See figure Buffer Structure.

If the user sequence is not used (i.e., ADC_MR.USEQ is cleared) then only the value of ADC_CHSR defines the data structure. For each trigger event, enabled channels will be consecutively stored in ADC_LCDR and automatically read to the buffer.

When the user sequence is configured (i.e., ADC_MR.USEQ is set) not only does ADC_CHSR modify the data structure of the buffer, but ADC_SEQR1 may modify the data structure of the buffer as well.
