(12) Debugging in 1-wire mode
Note the following points when debugging is performed in 1-wire mode (selected by choosing TOOL0 in the
Target Device Connection area in the Configuration dialog box of the debugger).
<1> The debugger operation speed is two to four times slower than that in 2-wire mode.
<2> When the internal high-speed oscillator is used for the CPU operating clock, breaks may not occur
normally if the frequency variation between debugger startup and break occurrence (except for when
changing the CKC register) is too large. This situation may occur when the variation of operating voltage
or temperature is too large.
(13) Pseudo real-time monitor function
Note the following points when using the pseudo real-time monitor function.
<1> The HALT mode is released during monitoring.
<2> The pseudo real-time monitor function does not operate while the CPU operating clock is stopped.
<3> A break may occur if the STOP mode is entered while the pseudo real-time monitor function being used.
