CHAPTER
5.2 On-Chip Debugging
This section describes the system configuration, startup/shutdown procedure and cautions for debugging when
on-chip debugging is performed with MINICUBE2.
5.2.1
Debug functions
Table 5-3 lists the debug functions when a 78K0S microcontroller is the target device and the ID78K0S-QB is
used.
If a debugger other than the ID78K0S-QB (made by partner manufacturer) is used, the available functions
may differ, so check the specifications of the debugger used.
Functions

Execution
Hardware break
Software break
Forced break
RAM monitoring
DMM (writing to memory during RUN)
Pin masking
Time measurement

User spaces used for debugging
Function pins used for debugging
Note The INTP pins to be used are described in the document "QB-MINI2 Operating Precautions".
The X1 and X2 pins are used only when the debugger is started for the first time (when downloading
the monitor program).
