2.9.3 A/D Conversion Bypass Capacitors

There is a foot pattern on the M30290T-EPBM board for mounting bypass capacitors for an A/D conversion circuit near the
MCU. Mount suitable bypass capacitors as occasion demands. Figure 2.21 shows where they are installed and the
configuration of this product.

Note on the A/D Converter Function:
Because a converter board and other devices are used between the evaluation MCU and the user system, the
A/D converter operates differently from that of an actual MCU. Make the final evaluation of the A/D converter
with an actual MCU.
