25.1 Internal Memory Size Switching Register
R01UH0028EJ0400 Rev.4.00
Sep 27, 2010
The 78K0/Kx2-L microcontrollers incorporates the flash memory to which a program can be written, erased, and
Select the internal memory capacity using the internal memory size switching register (IMS).
IMS is set by an 8-bit memory manipulation instruction.
Reset signal generation sets IMS to CFH.
Caution Reset signal generation makes the setting of the ROM area undefined. Therefore, set the value
Address: FFF0H
