ADC Prescaler

Slows the converter’s input clock down when dealing with XTAL frequencies above 100kHz. The
maximum clock frequency for the ADC is 200KHz (50KHz to 200KHz) so the main oscillator must
be prescaled appropriately.

ADC Channels Used

Selects which input lines (AD7..AD0)are to be used in multiplexed ADC operations. Any pins not
used can be used for standard digital inputs - Port F.
