High-Speed, High-Reliability Erasing: The H8/3048F 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 19.18 shows the basic
high-speed, high-reliability erasing flowchart. Tables 19.17 and 19.18 list the electrical
characteristics during programming.
