Table 15-8 Wait Time after P Bit Setting
Item
Wait time after P bit setting
Note: * Additional programming processing is necessary only when the reprogramming loop count
(n) is 1 to 6.
6. The program/program-verify flowchart for the H8/3022F is shown in figure 15-11.
To cover the points noted above, bits on which reprogramming processing is to be executed,
and bits on which additional programming is to be executed, must be determined as shown
below.
Since reprogram data and additional-programming data vary according to the progress of the
programming procedure, it is recommended that the following data storage areas (128 bytes
each) be provided in RAM.
