Notes 1. Connect TxD (transmit side) of the target device to RxD (receive side) of the target connector, and TxD
(transmit side) of the target connector to RxD (receive side) of the target device.

debugging, port settings made by the user program are ignored.
the pin must be connected as shown in this figure, because it is open when MINICUBE2 is not connected.
3. This connection is designed assuming that the RESET signal is output from the N-ch open-drain buffer
(output resistance: 100 Ω or less).
4. The circuit enclosed by a dashed line is designed for flash self programming, which controls the FLMD0 pin
via ports.
When not using flash self programming, process the pins according to the device specifications.
5. 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).
When changing the resistance, refer to APPENDIX A EQUIVALENT CIRCUIT and make sure that the
change does not affect operation before using the device.
6. To use FLMD1, connect it to FLMD1 of MINICUBE2.
