S32K344 EMIOS OUC problem

XPW — Tue, 02 Sep 2025 08:25:19 GMT

I have configured EMIOS0 with CH6 CH11 CH12 CH13 CH14 CH15, with a separate notification function for each channel. The problem now is that these notification functions no longer enter after a certain number of times.

I am glad to receive your reply. I have carefully reviewed the routine you provided, but the issue has not been resolved. I found that after no longer entering the OCU notification function, Interrupt handler for Emios channels 12-15 for Emios instance 0 is no longer triggered。（ISR(EMIOS0_2_IRQ)）

And at this point, return (0U!=(cpcxBase ->CH.UC [Channel]. C&eMIOS_C_SEN-MASK)? TRUE : FALSE; Always equal to TRUE
(0U != (cpcxBase->CH.UC[Channel].S & eMIOS_S_FLAG_MASK)) ? TRUE : FALSE; Always equal to False

Okay, I have identified the issue. When the newly written comparison value is 0, the situation I described earlier will occur
