For processing of signals MD, UB and EMLE, refer to section 2.5, Notes on Connection.
The output of the reset circuit of the user system must be open collector.
RxD1 and TxD1 signals are NOT required for debugging. These are only used for internal flash
programming with Renesas Flash Programmer.
The names in parentheses ( ) are pin names in the E1 and E20 14-pin connector when flash
memory is programmed using programming software. When programming flash memory, also
connect VCC, GND, and RES#.
