SAR Conversion clock is divided down from the system clock according to the AD1SC bits
(AD1SC3-0). The number of system clocks used for each SAR conversion clock is equal to
AD1SC + 1. (Note: the ADC1 SAR Conversion Clock should be less than or equal to
25 MHz). See Table 5.1 for conversion timing details.
AD1SCAL: System Calibration Enable.
0: Internal ground and reference voltage are used for offset and gain calibration.
