Write-only 

0: No effect.

1: Resets the ADC simulating a hardware reset.

0: No effect.

1: Begins analog-to-digital conversion.

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 conver-
sion 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).
