AFIO_RMP_CFG4.ADC4_ETRR bit to implement; if you select SWSTRRCH as the external trigger source, you
can start the regular channel conversion by setting ADC_CTRL2.SWSTRRCH to 1.

For the injection sequence , the software sets the ADC_CTRL2.EXTJTRIG bit to 1, then the injection channel can
use the rising edge of the external event to trigger the start conversion, and the software sets the
ADC_CTRL2.EXTJSEL[2:0] bits to select the external trigger source of the injection sequence. The external trigger
source selection is shown in the table below. If you select EXTI line 15 or TIM8_CC4 as the external trigger source,
you can set the AFIO_RMP_CFG.ADC1_ETRI or AFIO_RMP_CFG.ADC2_ETRI bit to implement; If you select
EXTI line 14 or TIM5_CC4 as the external trigger source, you can set the AFIO_RMP_CFG4.ADC3_ETRI or
AFIO_RMP_CFG4.ADC4_ETRI bit to implement; if you select SWSTRJCH as the external trigger source, you
can start the injection channel conversion by setting ADC_CTRL2.SWSTRJCH to 1.
