AD2SC4-0: ADC2 SAR Conversion Clock Period Bits
SAR Conversion clock is derived from system clock by the following equation, where
AD2SC refers to the 5-bit value held in AD2SC4-0. SAR conversion clock requirements are
given in Table 7.2.
UNUSED. Read = 0b. Write = don’t care.
AMP2GN1-0: ADC2 Internal Amplifier Gain (PGA)
00: Gain = 0.5
01: Gain = 1
10: Gain = 2
11: Gain = 4
*Note: AD2SC is the rounded-up result.
