Access:
• SWRST: Software Reset
0 = No effect.
1 = Resets the ADC simulating a hardware reset.
• START: Start Conversion
0 = No effect.
1 = Begins analog-to-digital conversion.
• TSCALIB: Touchscreen Calibration
0 = No effect.
1 = Programs screen calibration (VDD/GND measurement)
The calibration sequence is performed during the next sequence when command is launched during an already started
conversion sequence, or at the start of the second conversion sequence located after the TSCALIB command, if it is
launched when no conversion is in progress (sleep mode, waiting a trigger event).
TSCALIB measurement sequence does not affect the last data converted register (ADC_LDCR).
