3.4 A-D Conversion Bypass Capacitor
With this product, there is a socket (0.1 µF pre-mounted) on the board for changing the bypass
capacitor for the A-D conversion circuit. Remove or replace a suitable bypass capacitor as occasion
demands.
Figure 3.9 shows where the bypass capacitors are mounted, whereas Figure 3.10 shows an
enlargement of the foot patterns.

IMPORTANT
Note on the A-D Converter:
• Because a flexible board and other devices are used between the evaluation MCU
and the target system, the A-D converter operates differently from the actual MCU.
Make the final evaluation of the A-D converter from the actual MCU.
