Sample Time Select — These three bits select the length of the sample time in units of ATD conversion clock
cycles. Note that the ATD conversion clock period is itself a function of the prescaler value (bits PRS4-0).

ATD Clock Prescaler — These 5 bits are the binary prescaler value PRS. The ATD conversion clock frequency
is calculated as follows:
