Leave open the pins for which no name is shown in the figure for the 14-Pin Connector pin
assignment.
For processing of signals MD0, MD1 and EMLE, refer to section 2.5, Notes on Connection.
The output of the reset circuit of the user system must be open collector.
Note that TDO and TxD1, and TDI and RxD1 are assigned to different pins in the RX62T and
RX62G (112-pin version) group MCUs.
When writing to the MCUs of the RX62T and RX62G (112-pin version) Group using the Flash Development
Toolkit or the Renesas Flash Programmer, be aware that the pin assignments of the 14-pin connector differ than
otherwise.
For details on the flash programming software, refer to
