12.4. ZoomingADC register map
There are six registers in the acquisition chain (AC), namely CxZadcReg1, CxZadcReg2, CxZadcReg3, CxZadcReg4,
CxZadcReg5 and CxZadcReg6. Tables below shows the mapping of control bits and functionality of these registers while
Table 33 gives an overview of these six.
The register map only gives a short description of the different configuration bits. More detailed information is found in
subsequent sections.
