High-Speed, High-Reliability Erasing: The H8/3434F flash memory uses a high-speed, high-
reliability erasing procedure. This procedure provides enhanced erasing speed without subjecting
the device to voltage stress and without sacrificing data reliability. Figure 19.16 shows the basic
high-speed, high-reliability erasing flowchart. Tables 19.15 and 19.16 list the electrical
characteristics during erasing.
Note: *
Address + 1
Follow the high-speed, high-reliability programming flowchart in programming all bits. If some bits
are already programmed to 0, program only the bits that have not yet been programmed.
