Posted on May 07, 2013 at 15:29We're using RTC as a timer to wakeup STM32F103 from stop mode frequently, I'm quite confused on the descriptions in RM0008
1. what's the difference between
RTC_IRQHandler and
RTCAlarm_IRQHandler? If an alarm comes, both irq called? Is there a EXTI17_IRQHanlder?
2. do I must clear all of
EXTI_Line17,
PWR_FLAG_WU,
RTC_IT_ALR in some irq handler? what's the actual physical connection between the components that these registers reside on (plz help to explain based on Figure 179 in RM0008)?
Thanks a lot!
