In accordance with the Table 21-6, these 3 bits select the interrupt event which will generate the
trigger of the start of conversion. The start of conversion will be generated by the rising edge of
the selected interrupt flag whether the interrupt is enabled or not. In case of trig on PSCnASY
event, there is no flag. So in this case a conversion will start each time the trig event appears
and the previous conversion is completed

For trigger on any PSC event, if the PSC uses the PLL clock, the core must use PLL/4 clock
source.
