&par Example Description

    This example aims to show how to use WWDT.
    If  is_OverTime = 0 , System would not reset for feeding dog timely. LED2 Toggle.
    If  is_OverTime = 1 , System will reset. LED3 ON.

using USART1(TX:PA9, RX:PA10).
  - USART1 configured as follow:
  - BaudRate    = 115200
  - Word Length = USART_WordLength_8b
  - Stop Bit    = USART_StopBits_1
  - Parity      = USART_Parity_No
  - Hardware flow control disabled (RTS and CTS signals)
  - Receive and transmit enabled

  - WWDT/WWDT/Source/apm32e030_int.c        Interrupt handlers
  - WWDT/WWDT/Source/main.c                 Main program

&par Hardware and Software environment

  - This example runs on APM32E030 TINY Devices.
