CHAPTER 3: PERIPHERAL CIRCUITS (Power Supply)
3.2 Power Supply
The S1C621A0 is given 3 V by an single external power
supply and generates voltages needed to operate its LCD
driver and oscillation circuit.
A voltage reduction can be detected by the on-chip supply
voltage detection circuit. (See section 3.10 "AMP and SVD".)
The S1C621A0 uses its on-chip voltage regulator to generate
voltage level VS1 for stabilization of the oscillation circuit.
