Are NVIC_ICPR and NVIC_ISER still needed to enable interrupts?

[spchang2000]

I am using a KEA128 uC with Cyclone FX debugger.  I was able to configure RTC and saw RTC_CNT kept running.  RTC_SC_RTIF flag also got set periodically.  However, RTC_IRQHandler() never got called. I found a RTC example from TRK-KEA128_LABTS5/ where it has a routine called Enable_Interrupt() and NVIC_ICPR and NVIC_ISER are set accordingly.  Is this enabling routine still required?  Since, both of them are no longer defined in SKEAZ1284.h coming with the lastest S32 Design Studio for ARM.  Please advise.  Thanks!

Hi Shangpin,

Please download the FRDM-KEAZ Freedom Evaluation Board – QSP (REV 8 ) .

Then refer the FRDM_KEA128_RTC example. NVIC_ISER is needed to enable interrupt.

Best Regards,
Robin
