High-Speed, High-Reliability Programming: Unused areas of the flash memory in the
H8/3644F, H8/3643F, or H8/3642AF contain H'FF data (initial value). The flash memory uses a
high-speed, high-reliability programming procedure. This procedure provides higher programming
speed without subjecting the device to voltage stress and without sacrificing the reliability of the
programmed data.
Figure 6.18 shows the basic high-speed, high-reliability programming flowchart. Tables 6.15 and
6.16 list the electrical characteristics during programming.
