Flash Memory
The M16C/26 (flash memory version) contains the flash memory that can be rewritten with a single voltage.
For this flash memory, three flash memory modes are available in which to read, program, and erase:
parallel I/O and standard serial I/O modes in which the flash memory can be manipulated using a program-
mer and a CPU rewrite mode in which the flash memory can be manipulated by the Central Processing Unit
(CPU). Each mode is detailed in the following sections.
The flash memory is divided into several blocks as shown in Figure 1.19.1, so that memory can be erased
one block at a time.

Note 1: To specify a block, use the maximum address in the block
that is an even address.
Note 2: To access 2Kbyte data blocks, set PM10 to "1".
