Notes 1. In
μPD78F921x, 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).
2. In
μPD78F921x, VSS functions alternately as the ground potential of the A/D converter. Be sure to
connect VSS to a stabilized GND (= 0 V).
