Bit7
The 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 (Note: the ADC0 SAR Conversion Clock should be less than or equal to
2.5 MHz).
When the AD0SC bits are equal to 00000b, the SAR Conversion clock is equal to SYSCLK
to facilitate faster ADC conversions at slower SYSCLK speeds.
