Dear all :
in our project, ADC is a safety function module, so its hardware selftest should been executed to ensure ADC integrity.
Assumption under certain conditions: [SM_130] When Analog-to-Digital Converter (ADC) of the MPC5744P are used in a safety function, suitable system level functional safety integrity measures must be implemented after reset (external reset or destructive reset) before starting the respective safety function to ensure ADC integrity.
Assumption under certain conditions: [SM_131] Before running the ADC hardware self-test, the system software must copy the reference thresholds from UTest flash memory to the watchdog registers (STAWnR).
Assumption under certain conditions:[SM_132] When using integrated self-test as the functional safety integrity measure, the analog watchdog for CPU and CTU modes must be enabled for the self-test. The programmable watchdog timeout is smaller than the FTTI.
Please tell us how can we use ADC hardware selftest function , can you provide any sofeware sample for us ?
