42.8.1 ADC Control Register
Name: ADC_CR
Address: 0xF804C000
Access: Write-only
• 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 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).
