Bits7-3: AD0SC4-0: ADC0 SAR Conversion Clock Period Bits.
SAR Conversion clock is derived from FCLK by the following equation, where AD0SC refers
to the 5-bit value held in bits AD0SC4-0. SAR Conversion clock requirements are given in
Table 5.3.
BURSTEN = 0: FCLK is the current system clock.
BURSTEN = 1: FCLK is a maximum of 25 MHz, independent of the current system clock.

Bits2-1: AD0RPT1-0: ADC0 Repeat Count.
Controls the number of conversions taken and accumulated between ADC0 End of
Conversion (ADCINT) and ADC0 Window Comparator (ADCWINT) interrupts. A convert
start is required for each conversion unless Burst Mode is enabled. In Burst Mode, a single
convert start can initiate multiple self-timed conversions. Results in both modes are
accumulated in the ADC0H:ADC0L register. When AD0RPT1-0 are set to a value other
than '00', the AD0LJST bit in the ADC0CN register must be set to '0' (right justified).
00: 1 conversion is performed.
01: 4 conversions are performed and accumulated.
10: 8 conversions are performed and accumulated.
11: 16 conversions are performed and accumulated.
