If this LSI is restarted by a power-on reset immediately after user MAT programming has
finished, secure a reset period (period of RES = 0) that is at least as long as normal 100 μs.
Programming finished area
programming operations have been performed to the same block, programming finished
processing should only be carried out once. (Due not perform programming finished
processing multiple times.) If it is necessary to reprogram blocks within a previously
programmed area on which programming finished processing has been performed, first
erase the blocks in question and then reprogram them.
have been programmed after initialization processing. For example, if programming
finished processing is to be carried out once after programming blocks EB1 to EB3,
programming finished processing should be performed individually on EB1, EB2, and
EB3.
the necessary data has completed. Caution is necessary because if an operation such as
initialization processing, internal program downloading, rewriting an area of RAM that is a
download destination, or MAT switching is performed before programming finished
processing, programming will not take place correctly.

Before reprogramming erased blocks containing a programming
finished area (EB10 and EB11), the corresponding erased
blocks (EB10 and EB11) should be erased.
