High-Speed, High-Reliability Programming: Unused areas of the H8/3048F flash memory
contain H'FF data (initial value). The H8/3048F flash memory uses a high-speed, high-reliability
programming procedure. This procedure provides enhanced programming speed without
subjecting the device to voltage stress and without sacrificing the reliability of programmed data.
Figure 19.17 shows the basic high-speed, high-reliability programming flowchart. Tables 19.17
and 19.18 list the electrical characteristics during programming.
