When reading data from ADCx_DR (regular channel) or from ADCx_JDRy (injected
channel, y=1,2,3,4) corresponding to the channel "i":
•
If one of the offsets is enabled (bit OFFSETy_EN=1) for the corresponding channel, the
read data is signed.
• If none of the four offsets is enabled for this channel, the read data is not signed.
