Analog-to-digital converter (ADC)
Bits 15:0 DATA[15:0]: Converted data
These bits are read-only. They contain the conversion result from the last converted channel. The data
are left- or right-aligned as shown in
Just after a calibration is complete, DATA[6:0] contains the calibration factor.

Note: Software is allowed to write this bit only when ADSTART=0 (which ensures that no conversion
is ongoing).
Bit 23 TSEN: Temperature sensor enable
This bit is set and cleared by software to enable/disable the temperature sensor channel.
0: Temperature sensor and V
1: Temperature sensor and V
Note: Software is allowed to write this bit only when ADSTART=0 (which ensures that no conversion
is ongoing).
