I am testing the ADC and ADC_ETC (see my other threads).
During this testing I am seeing intermittently that the trigger result register isn't available immediately in the done interrupt.
In my test code, I am setting a variable to store the current result value in the done interrupt, but it is sometimes getting the previous value. If I put a (1mS) delay in before setting the variable, it always gets the correct value from the result register.
Here is my example interrupt code that is not behaving as expected.
g_AdcConversionDoneFlag = true;
g_AdcConversionValue = ADC_ETC_GetADCConversionValue(ADC_ETC, 0U, 0U); /* Get trigger0 chain0 result. */
ADC_ETC_ClearInterruptStatusFlags(ADC_ETC, kADC_ETC_Trg0TriggerSource, kADC_ETC_Done0StatusFlagMask);
It seems that the result register is supposed to be updated *before* the interrupt fires?
