27.1 Internal Memory Size Switching Register
R01UH0008EJ0401 Rev.4.01
Jul 15, 2010
The 78K0/Kx2 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 Be sure to set each product to the values shown in Table 27-1 after a reset release.
Caution To set the memory size, set IMS and then IXS. Set the memory size so that the internal ROM and
