In the 78K0S/KA1+, VSS functions alternately as the ground potential of the A/D converter. Be sure to
connect VSS to a stabilized GND (= 0 V).
Excludes quantization error (±1/2 LSB).
This value is indicated as a ratio (%FSR) to the full-scale value.
Caution The conversion accuracy may be degraded when the analog input pin is used as an alternate I/O
port or if a port is changed during A/D conversion.
