Note: The S5U1C1700H incorporates a 7-V, 200-mA power supply for flash programming. However, use of this power
supply may not be possible with certain S1C processors. If the technical manual for the target S1C processor
does not specifically mention this power supply, damage may occur in the chip due to overvoltage. To prevent this
problem, avoid using this voltage (do not set the DIP SW8 to ON) if this voltage is not supported by the target S1C
processor.
