Notes 1.

In the 78K0S/KY1+, 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 the 78K0S/KY1+, VSS functions alternately as the ground potential of the A/D converter. Be sure to

connect VSS to a stabilized GND (= 0 V).

3.

Excludes quantization error (

±1/2 LSB).

4.

This value is indicated as a ratio (%FSR) to the full-scale value.

5.

A value when HALT mode is set by an instruction immediately after A/D conversion starts.

Caution The conversion accuracy may be degraded if the level of a port that is not used for A/D conversion

is changed during A/D conversion.
