22. Flash Memory Version
Aside from the built-in flash memory, the flash memory version microcomputer has the same functions as the masked
ROM version.
In the flash memory version, the flash memory can perform in three rewrite modes: CPU rewrite mode, standard serial
I/O mode and parallel I/O mode.
Table 22.1 lists specifications of the flash memory version. See Table 1.1 to Table 1.3 Performance outline of
M16C/62PT group for the items not listed in Table 22.1.

1. The boot ROM area contains a standard serial I/O mode rewrite control program which is stored in it
2. Can be programmed in byte units in only parallel input/output mode.
3. Block 1 and block A are 10,000 times of programming and erasure. All other blocks are 1,000 times
4. Definition of program and erase endurance
when shipped from the factory. This area can only be rewritten in parallel input/output mode.
of programming and erasure.
The programming and erasure times are defined to be per-block erasure times. For example,
assume a case where a 4-Kbyte block A is programmed in 2,048 operations by writing one word at
a time and erased thereafter.
In this case, the block is reckoned as having been programmed and erased once.
If a product is 100 times of programming and erasure, each block in it can be erased up to 100
times. When 10,000 times of programming and erasure, block 1 and block A can each be erased
up to 10,000 times. All other blocks can each be erased up to 1,000 times.
