21. Flash Memory Version
Aside from the on-chip flash memory, the flash memory version MCU has the same functions as the masked
ROM version.
In the flash memory version, the flash memory can perform in four rewrite mode: CPU rewrite mode, standard
serial I/O mode, parallel I/O mode, and CAN I/O mode.
Table 21.1 lists the Flash Memory Version Specifications. See Table 1.1 Functions and Specifications,
for the items not listed in Table 21.1. Table 21.2 shows the Flash Memory Rewrite Modes Overview.

1. The PM13 bit remains set to 1 while the FMR01 bit in the FMR0 register = 1 (CPU rewrite mode enabled). The PM13 bit

it when shipped from the factory. This area can only be rewritten in parallel I/O mode.
The programming and erasure endurance is defined to be per-block erasure endurance. For example, assume a case where
a 4K-byte 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 endurance, each block in it can be erased up to 100 times.

changed during CPU rewrite mode, its changed value is not reflected until after the FMR01 bit is set to 0.
