  This example is based on the GD32M531R-EVAL-V1.2 board, it demonstrates the scan once
operation in the bifurcate trigger mode of the ADC.
  The ADC trigger sources are selected as TIMER0_TRGA and TIMER0_TRGB. When the rising edge
of TIMER0_TRGA arrives, the ADC starts conversion. After the conversion is completed, the
result is stored in the ADC0_CH4DATA. When the rising edge of TIMER0_TRGB arrives, the ADC
starts conversion. After the conversion is completed, the result is stored in the ADC_GP1BIDATA
register, and at the same time, EOC1RF is set, generating an interrupt request. In the interrupt
service function, the conversion result is obtained and the result is output through the COM.
  When the program runs, the LED will keep blinking.
  JP18 needs to be connected.
