  This demo is based on the GD32350R-EVAL board, it shows how to use the
ADC to convert analog signal to digital data. The ADC is configured in
dependent mode, inner channel 16(temperature sensor channel) and channel 
17(VREF channel) are chosen as analog input pin.

  As the ADC convertion begins by software, the converted data in the 
ADC_IDATAx register,where the x is 0 to 1.

  Jump the JP13 to USART.
