RM44L520: SL_SelfTest_ADC

Part Number: RM44L520

Dear team,

In the diagnostic library, boolean SL_SelfTest_ADC(SL_SelfTestType testType, boolean mode, SL_ADC_Config * config, SL_ADC_Pinstatus * pinstatus); in the pinstatus pin status parameter.

Why the corresponding pin is connected to a fixed voltage, it always returns different? Sometimes it returns ADC_PIN_GOOD, sometimes it returns ADC_PIN_SHORTED_TO_ADVREF_LOW, and sometimes it returns ADC_PIN_UNDETERMINED.

The customer Increased the sampling time, such as 20us and tried it. It always returns different.

Please help.
