dialog box, the clock source of the device is changed to the clock from QB-78K0MINI during a break. If the
peripheral emulation function does not stop (by selecting "Non Break" for "Peripheral Break"), due to clock
changes, timing may differ from the timing in the actual operation. In order to adjust the clock timing even during
a break, mount an oscillator with the same frequency as the actual clock, in QB-78K0MINI.

If the debugger does not terminate normally due to a factor such as a freeze while a software break is set, the
