The A/D system is an 8-channel, 8-bit, multiplexed-input converter. The
VDD AD and VSS AD pins are used to input supply voltage to the A/D
converter. This allows the supply voltage to be bypassed independently.
The converter does not require external sample and hold circuits
because of the type of charge redistribution technique used. A/D
converter timing can be synchronized to the system E clock, or to an
internal resistor capacitor (RC) oscillator. The A/D converter system
consists of four functional blocks: multiplexer, analog converter, digital
control and result storage. Refer to
