Hi, I have imported Demo project "rtc_alarm_s32k144" to S32DS ,However ,I found the Interrupt peroid is not 1 second in function "secondsISR()", Actually it is far less than 1 second。
On the other way, it will work well if i change ".clockSelect" to RTC_CLK_SRC_LPO_1KHZ, as below.
Can somebody tell me why? Thanks.
Hi,
The LPOCLKS[RTCCLKSEL] register is a write-once register.
It is reset only on POR or LVD.
So please run the code from Flash, not RAM, and power-on reset the MCU.
Regards,
Daniel
