Section 15 A/D Converter
15.5
The A/D converter generates an interrupt (ADI) at the end of A/D conversion. The ADI interrupt
request can be enabled or disabled by the ADIE bit in ADCSR.
15.6
When using the A/D converter, note the following points:
1. Analog Input Voltage Range: During A/D conversion, the voltages input to the analog input
2. Relationships of AV
3. V
Failure to observe points 1, 2, and 3 above may degrade chip reliability.
4. Note on Board Design: In board layout, separate the digital circuits from the analog circuits as

much as possible. Particularly avoid layouts in which the signal lines of digital circuits cross or
closely approach the signal lines of analog circuits. Induction and other effects may cause the
analog circuits to operate incorrectly, or may adversely affect the accuracy of A/D conversion.
