  This demo is based on the GD32M531R-EVAL-V1.2 board, it shows the WWDGT with different
counter value and window value make the different WWDGT timeout. As a result, LED1
and LED2 display a different phenomenon.

  In this demo, the WWDGT counter value is set to 16383, the refresh window is set from
15000 to 12888. In this case the WWDGT window time is set from 503ms to 1490ms(the timeout
may varies due to APB1 frequency dispersion), the value in the delay function is set to
800ms, the WWDGT counter can reloaded normally,the LED1 is turn off, LED2 is blinking
regularly.

  If the value in the delay function is not set properly, the WWDGT counter is not
reloaded. As a result, the system reset and only the LED1 is remain illuminated.

  In this example the system clock is set to 180 MHz , and the APB1 is set to 90MHz.
