Starting a conversion involves to do a conversion for all active channel. It starts with ADC channels and ends with touchscreen channels. Then if ADC_LCD register is not read quickly, its content may be a touchscreen conversion. To remove this temporal constraint, the conversion value is taken from the channel data register.
