The following paragraphs describe the operation and performance of
analog modules within the analog subsystem.
The A/D converter is ratiometric, with pin V
reference voltage. Applying an input voltage equal to V
conversion result of $FF (full scale). Applying an input voltage equal to

referenced to V
The reference supply for the A/D converter shares pin PC7 with port C.
The low reference is tied to the V

The 8-bit conversion result is accurate to within
significant bit), including quantization; however, the accuracy of
conversions is tested and guaranteed only with external oscillator
operation.
The A/D reference inputs are applied to a precision digital-to-analog
(D/A) converter. Control logic drives the D/A and the analog output is
successively compared to the selected analog input that was sampled at
