1.12 Notes for the Diagnostics
- SCB entry in DIA_REGx see diagrams in chapter 1.6.4.
- In case of overvoltage at pin VDD (VDD > 5,5V) the diagnostic information can be wrong. In
that case, the diagnostic information has to be cleared with the DEL_DIA instruction.
- The filtering time restarts when the output voltage passes the diagnostic threshold for
short to ground (SCG).
