to these specifications. Also, when using the integrated debugger with the QB-78K0MINI to start debugging (i.e.,
when reading the target device’s on-chip flash memory code), enter the ID code in the integrated debugger’s
configuration screen and perform ID code authentication.
123456789ABCDEF123D4 or 123456789abcdef123d4.
Microcontrollers that include flash memory include an authentication function that reads an embedded 10-byte ID
This ID code’s specifications are described below. Be sure to write the ID code to on-chip flash memory according
[ID code specifications]
• The values of addresses 0x85 to 0x8E comprise the 10-byte ID code.
• Bits 0 and 1 at address 0x84 are the use enable flag bits for the QB-78K0MINI (“00b” = use prohibited, any
• If the ID code input to the integrated debugger matches the ID code embedded in the on-chip flash memory,
• Even if these two ID codes match, debugging cannot be performed when the QB-78K0MINI use enable flag
• When flash memory contents are erased, its ID code becomes 0xFFFFFFFFFFFFFFFFFFFF.
Caution Of “00” is written to address 0x84, write operations from the QB-78K0MINI become disabled, and
The following is an ID code setting example.
