Notes 1.

In the

µPD78F9210CS, 78F9211CS, 78F9212CS, VSS functions alternately as the ground potential of the

A/D converter. Be sure to connect VSS to a stabilized GND (= 0 V).

2.

In the

µPD78F9210CS, 78F9211CS, 78F9212CS, VDD functions alternately as the A/D converter reference

voltage input. When using the A/D converter, stabilize VDD at the supply voltage used (2.7 to 5.5 V).
