Notes 1. If there are capacitance elements such as capacitors, on-chip debugging might not operate normally.
2. The clock signal generated by the clock circuit on the target system or by the internal high-speed oscillator
of the device can be used for the clock signal of the target device during on-chip debugging.
Only the internal high-speed oscillator of the device can be used during flash programming.
3. During on-chip debugging, the settings specified by the user program are ignored, because these pins are
used as pins dedicated to on-chip debugging. However, if the pins are specified as input pins, the pins
must be processed (because they are left open when MINICUBE2 is not connected.)
4. This is the processing for the pins that are unused (the inputs are left open) when the target device
operates (when MINICUBE2 is not connected).
output.)
When changing the resistance, refer to APPENDIX A EQUIVALENT CIRCUIT and make sure that the
change does not affect operation before using the device.
5. This connection is designed assuming that the RESET signal is output from the N-ch open-drain buffer
(output resistance: 100 Ω or less).
