16.3 Register map
There are eight registers in the acquisition chain (AC), namely RegAcOutLsb, RegAcOutMsb, RegAcCfg0,
RegAcCfg1, RegAcCfg2, RegAcCfg3, RegAcCfg4 and RegAcCfg5. Table 16-2 to Table 16-9 show the mapping
of control bits and functionality of these registers while Table 16-1 gives an overview of these eight.
The register map only gives a short description of the different configuration bits. More detailed information is found
in subsequent sections.
