• Manufacturer Part Number: MC68HC705T16
• Description: High-density complementary metal oxide semiconductor (HCMOS) microcontroller unit
• Manufacturer: MOTOROLA [Motorola, Inc]

The Analog-to-Digital Converter (ADC) system consists of two analog input channels and a single
5-bit D/A Converter and Comparator, with continuous conversion. A result flag indicates if the
comparator output is above or below the analog Input. ADC is disabled by setting AD4 to AD0 bits
of ADC Control/Status register to all 1’s. This disable function is mainly for low power applications.
Figure 10-1 shows a block diagram of the ADC module.
