42.7.10.3 Interleaved Channels
When both classic ADC channels (CH4/CH5 up to CH12 are set in ADC_CHSR) and touchscreen conversions are
required (TSMODE differs from 0 in ADC_TSMR register) the structure of the buffer differs according to TSAV and
TSFREQ values.
required (TSMODE differs from 0 in ADC_TSMR register) the structure of the buffer differs according to TSAV and
TSFREQ values.
If TSFREQ differs from 0, not all events generate touchscreen conversions, therefore buffer structure is based on

trigger events. Given a TSFREQ value, the location of touchscreen conversion results depends on TSAV value.
When TSFREQ = 0, TSAV must equal 0.
There is no change in buffer structure whatever the value of PENDET bit configuration in ADC_TSMR register but it is
recommended to use the pen detection function for buffer post-processing (refer to
