When the 128-byte programming or one-block erasure does not end the processing, the
program address/data and erase-block number must be updated and consecutive
programming/erasing is required.
Since the downloaded on-chip program remains in the on-chip RAM even after the processing
ends, download and initialization are not required when the same processing is executed
consecutively.
