Notes 1.
In the 78K0S/KU1+, V
SS
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 the 78K0S/KU1+, V
DD
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).
