For processing of signals UB, refer to section 2.5, Notes on Connection.
The output of the reset circuit of the user system must be open collector.
Connect the RxD1 and TxD1 pins when flash memory is programmed through the SCI.
When flash memory is programmed through the FINE interface, they do not need to be
connected.
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#.
