Hello,

I have a problem understanding the behavior of the adc burst mode,

I configure the adc in burstmode with 400khz

I am calling

Chip_ADC_ReadValue

in an Interrupt triggered by the mcpwm. However I sometimes get "ERROR" as a return value. I guess it is caused by an ADC overrun. Is the value that in the ADC Register still valid but values were lost or is it corrupted? Is it possible to just get the last valid value that was read by the ADC?

Kind regards
