This bit restricts the hardware protect functions during write and erase operations for the flash
memory. For details on hardware protect, see section 19.5.8, “Protect Modes.” For notes on VPP
usage, see section 19.8, “Flash Memory Programming and Erasing Precautions (Dual-Power

and erasing cannot be performed until stabilization is complete. After this bit is cleared, it is
necessary to wait for the flash memory read setup time (t
Note: The power supply system used for the flash memory is switched by means of the VppE bit.

After switching, operation is not guaranteed during the period before the power supply
