26.1 Internal Memory Size Switching Register
The 78K0/LF2 incorporates the flash memory to which a program can be written, erased, and overwritten while
The internal memory capacity can be selected 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 26-1 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

internal expansion RAM areas do not overlap.
The ROM and RAM capacities of the products with the on-chip debug function can be debugged
according to the debug target products. Set IMS and IXS according to the debug target products.
However, the set value of IMS of these devices is the same as those of the 48 KB product because
memory banks are used. For how to set the memory banks, see 3.6 Memory Bank Select Register
(BANK) ( PD78F0376, 78F0376D, 78F0386, AND 78F0386D ONLY).
