Notes 1. In
μ PD78F920x, VSS functions alternately as the ground potential of the A/D converter. Be sure to
connect V
SS to a stabilized GND (= 0 V).
2. In
μ PD78F920x, VDD functions alternately as the A/D converter reference voltage input. When using the
A/D converter, stabilize V
DD at the supply voltage used (2.7 to 5.5 V).
