Hello,
I am using RTC Wakeup timer in STM32F469NIH6 processor. Low level access is using HAL code.
I's is configured with
RTC.CR.WCKSEL = 0x3
RTC.WTR.WUT = 1
EXTI.IMR.MR22 is set
EXTI.RSTR.M22 is set.
It generates RTC Wakeup Interrupt ~122.09usec. interval for about .8sec. After that no more interrupt.
RTC.ISR.WUTF is set
EXTI.PR.M22 is not set
What could be the reason for not generating interrupt any more.
Thanks.
