  This example is based on the GD32C231C-EVAL-V1.0 board, it shows pmu how to enter
standby mode and wakeup it.
  After startup, mcu will enter standby mode after 2 seconds, and leds turn off. When you
press WAKEUP key(PA0), mcu will be wakeuped from standby mode, led will be turn on.
  when exit from the standby mode, a power-on reset occurs and the mcu will execute instruction
code from the 0x00000000 address.
