NOTES:
The flash memory version has two modes—CPU rewrite and standard serial I/O—in which its flash
memory can be operated on.
Table 17.1 outlines the performance of flash memory version (see “Table 1.1 Performance” for the items
not listed on Table 17.1).

1: Definition of program/erase times
The program/erase times are defined to be per-block erase times. When the program/erase times
are n times (n=1,000 or 10,000 times), to erase n times per block is possible. For example, if
performing one-byte write to the distinct addresses on the Block A of 2K-byte block 2,048 times and
then erasing that block, the number of the program/erase cycles is one time. if rewriting more than
1,000 times, run the program until the vacant areas are all used to reduce the substantial rewrite
times and then erase. Avoid rewriting only particular blocks and rewrite to average the program and
erase times to each block. Also keep the erase times as inrformation and set up the limit times.
