SPC5744P CTU

[haizhouyan]

When spc5744p CTU is selected to trigger the ADC and complete the data conversion, an EOCTU will be set in the ADC_ISR register, but it cannot mean that any channel selected by CTU has completed the conversion, unlike normal mode where the corresponding EOC in ADC_CEOCFR0 is read to see which channel has completed the conversion.What if I want to know exactly whether one or more ADC channels selected and triggered by CTU have completed the conversion?Are the corresponding bits in ADC_CEOCFR0 lost as well?

Hi,

yes in CTU mode the CEOCFRx is not updated, just EOCTU is set and data registers are updated.

But usually the conversion data are read through CTU FIFO where the result are stored after each channel conversion completion. Each FIFO entry contains converted value, channel and ADC module number.
