(9) Timing at which A/D conversion result is undefined

The A/D conversion value may be undefined if the timing of completion of A/D conversion and the timing of
stopping the A/D conversion conflict with each other. Therefore, read the A/D conversion result before stopping
the A/D conversion operation.
Figure 13-16 shows the timing of reading the conversion result.
Locate analog circuits as far away from digital circuits as possible on the board because the analog circuits may
be affected by the noise of the digital circuits. In particular, do not cross an analog signal line with a digital signal
line, or wire an analog signal line in the vicinity of a digital signal line. Otherwise, the A/D conversion
characteristics may be affected by the noise of the digital line.

Therefore, be sure to apply the same potential as V
