5.2.10. Current Multiplexer Test
Event
There is a failure in the current multiplexer or the current to voltage converter
Detection
A dedicated diagnostic channel of the current multiplexer with fixed current level is connected to
the ADC. The expected result is 10% of the ADC unsigned full-scale range.
Details for software implementation:
ADC channel selected by ADCCTRL register: IMPSEL[4:0] = 1Fh
Expected ADC conversion result:
ADCRES[9:0] = 102 ± 10 (unsigned result)
Capturing The event is captured in MCU by reading the ADC conversion value
Reaction
Should be implemented in MCU software depending on the application requirements.
