AD0SC4-0: ADC0 SAR Conversion Clock Period Bits
SAR Conversion clock is derived from system clock by the following equation, where
AD0SC refers to the 5-bit value held in AD0SC4-0, and CLK
SAR clock. See Table 5.2 for SAR clock configuration requirements.
AMP0GN2-0: ADC0 Internal Amplifier Gain (PGA)
000: Gain = 1
001: Gain = 2
010: Gain = 4
011: Gain = 8
10x: Gain = 16
11x: Gain = 0.5
*Note: AD0SC is the rounded-up result.
