  this demo is based on the ht32f49163_sk board, in this demo, shows how to use
  the exint line trigger source trigger adc in partitioned mode.
  the convert data as follow:
  - adc1_ordinary_valuetab[0]  ---> adc1_channel_4
  - adc1_ordinary_valuetab[1]  ---> adc1_channel_5
  - adc1_ordinary_valuetab[2]  ---> adc1_channel_6
  - adc1_preempt_valuetab[0]   ---> adc1_channel_7
  - adc1_preempt_valuetab[1]   ---> adc1_channel_8
  - adc1_preempt_valuetab[2]   ---> adc1_channel_9
  trigger source:
  - ordinary   -->  exint line11(pc11)
  - preempt    -->  exint line15(pa15)
