D.3 Turning On and Off Between the Same Power Supply Series
The order of the power supply in the VDD10 series, the VDD18 series and the VDD33 series
power supply is as follows.
Figure D.3 is an explanation chart of VDD10. The regulation of the potential difference is the
same VDD10 as the other (VDD10, VDD33).
• Turning On Power Supply
There is no restriction for the order of the power supply between each power supply series
except that the potential difference of the one power supply series is less than 0.3V.
• Turning Off Power Supply
There is no restriction for the order of the power supply between each power supply series
except that the potential difference of the one power supply series is less than 0.3V.
