The AWD comparison is performed at the end of each ADC conversion. The
ADC_AWDx_OUT rising edge and falling edge occurs two ADC_CLK clock cycles after the
comparison.
As ADC_AWDx_OUT is generated by the ADC_CLK domain and AWD flag is generated by
the APB clock domain, the rising edges of these signals are not synchronized.
