26.2 Internal Expansion RAM Size Switching Register
(IXS).
26.3 Writing with Flash Programmer
(1) On-board programming
(2) Off-board programming
544
The internal expansion RAM capacity can be selected using the internal expansion RAM size switching register
IXS is set by an 8-bit memory manipulation instruction.
Reset signal generation sets IXS to 0CH.
Caution Be sure to set each product to the values shown in Table 26-2 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
Data can be written to the flash memory on-board or off-board, by using a dedicated flash programmer.
The contents of the flash memory can be rewritten after the 78K0/LF2 has been mounted on the target system.
The connectors that connect the dedicated flash programmer must be mounted on the target system.
Data can be written to the flash memory with a dedicated program adapter (FA series) before the 78K0/LF2 is
mounted on the target system.
