SAR Conversion clock is divided down from the system clock according to the AD0SC bits
(AD0SC3-0). The number of system clocks used for each SAR conversion clock is equal to
AD0SC + 1. (Note: the ADC0 SAR Conversion Clock should be less than or equal to
25 MHz). See Table 5.1 for conversion timing details.
