When debugging with QB-MINI2 connected:

Other than above:
2-3 shorted
Caution If debugging is performed with a real machine running, without using QB-MINI2, write the user
program using the QB-Programmer. Programs downloaded by the debugger include the monitor
program, and such a program malfunctions if it is not controlled via QB-MINI2.
17.1.2 Connection of X1 and X2 pins
The X1 and X2 pins are used when the debugger is started for the first time (when downloading the monitor
program) and when programming is performed with the QB-Programmer.
