The voltage down converter (VDC) is a circuit used to step down external supply voltage to the internal
operation voltage of 3.3V. Disconnect the VDC when applying a 3.3V supply voltage to reduce power
consumption.
Figure 27.3 shows the procedure for disconnecting the VDC.
Perform these settings immediately after reset, while the CPU clock is divided by 8. Do not set the VDC0
register (001B
voltage of 3.3V or more.
