Section 24 Flash Memory

When Programming/Erasing is Executed Consecutively
When processing does not end by 128-byte programming or 1-block erasure, consecutive
programming/erasing can be realized by updating the start address of the programming destination
and program data, or the erase block number. Since the downloaded on-chip program is left in the
on-chip RAM even after programming/erasing completes, download and initialization are not
required when the same processing is executed consecutively.
