Flash Memory
The M16C/6KA (build-in flash memory version) contains the NEW DINOR type flash memory, which is
applied VCC=3.3V when using CPU reprogram or standard serial I/O mode. For the flash memory, 3 flash
memory modes are available in which to read, program and erase. They are parallel I/O mode, standard
serial I/O mode and CPU reprogram mode. For parallel I/O mode, a programmer is used. For standard serial
I/O and CPU reprogram modes, the flash memory is manipulated by CPU. Each mode is detailed in the
pages to follow.
Fig. AB-1 shows that flash memory is divided into several blocks. Erasing is in block unit.
In addition to the ordinary user ROM area there is a boot ROM area to store the control program for the CPU
reprogram and standard serial I/O modes. The control program for standard serial I/O mode is stored in boot
ROM area when shipping from factory. User can reprogram the program to suit its own application system.
The area can only be erased or programmed by parallel I/O mode.

Boot ROM area (Note 1)
Note 1: Boot ROM area can be reprogrammed only in parallel
I/O mode. (Access to any other areas is inhibited.)
Note 2: To specify a block, use the maximum even address in
the block.
