Requests are sent to the L9679E IC via the ADC measurement Registers (ADCREQx) as shown in
Table 14. Diagnostics control register (DIAGCTRLx). All diagnostics results are available on the ADCRESx
registers, when addressed by the related ADCREQx register (e.g. data requested by ADCREQA would be written
to ADCRESA).
