When both classic ADC channels (CH4/CH5 up to CH12 are set in ADC_CHSR) and touch-
screen conversions are 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 2
screen conversion results depends on TSAV value.
