This demo is based on the GD32307C-EVAL-V1.1, it explains how to configure the
RTC module to wake up MCU from deepsleep and feed dog in RTC alarm interrupt.
Select RCU_IRC40K as RTC and FWDGT clock source. The RTC alarm interval is 2s and the
FWDGT timeout is configured as 8s.
After start-up, the LED2 is off and the LED5 is on. After 2 seconds, LED5 is off and the
MCU enters deepsleep mode. MCU is waked up by RTC alarm every 2 seconds. After wakeup, LED2
is toggled, then MCU enters deepsleep mode again.
