High-Speed, High-Reliability Programming: Unused areas of the H8/3437F flash memory
contain H'FF data (initial value). The H8/3437F 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 20.15 shows the basic high-speed, high-reliability programming flowchart. Tables 20.15
and 20.16 list the electrical characteristics during programming.
