When the analog dimmer is selected, the analog voltage applied to this pin controls the duty of the G1
and G2 digit output pins. Since a 6-bit A/D converter is applied to this analog voltage and that result is
input to a decoder that provides a built-in dimmer curve, the relationship between the analog voltage
and the duty can be specified as a mask program. Note that 63/96 · V
