In μPD78F920x, 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).
In μPD78F920x, 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.
A value when HALT mode is set by an instruction immediately after A/D conversion starts.
Caution The conversion accuracy may be degraded when the analog input pin is used as an alternate I/O port
or if the level of a port that is not used for A/D conversion is changed during A/D conversion.
