There is a critical inconsistency identified between ADC specification and actual register value for ADC_SC1x.

 

Actual value in S32DS:

ADCH field only has 5 bits available and setting 0x1F disables it.Actual register value

These are the register values in memory window:

CPU specification:

ADCH field has 6 bits available and setting 0x3F disables it, while 0x1F is a reserved value.
