7.2.5 Flash memory ID code
This MCU function prevents the Flash memory from being read out by anyone other than the user.
The ID code in Table 7.5 written to the flash memory of the MCU must match the ID code displayed in the Figure
7.1 [ID Code verification] Dialog Box at debugger startup, otherwise the debugger cannot be launched. Note that
when the ID code is FFh, FFh, FFh, FFh, FFh, FFh, FFh, the ID code is regarded as undefined. In this case, the ID
code is automatically authenticated and the [ID Code verification] dialog box is not displayed.
The values written into the ID code area differs depending on the mode.
- ‘Program Flash’ mode:
Contents of the user program
- Modes other than ‘Program Flash’ mode: FFh, FFh, FFh, FFh, FFh, FFh, FFh
(regardless of the contents of the downloaded user program)

Notes
Notes on ‘Program Flash’ mode:
z When the ID code is specified by the -ID option of the lmc30, download the MOT file or HEX file.
z When the X30 file is downloaded, the ID code is not valid. When downloading the X30 file, specify the ID code
using an assembler directive command such as “.BYTE”.
z The file to which the ID code specified by the assembler directive command “.ID” is output varies depending on
the version of the assembler. For details, refer to the Assembler User’s Manual.
