Connecting the E10A-USB Emulator with the User System

Before connecting an E10A-USB emulator (hereafter referred to as emulator) with the user
system, a connector must be installed in the user system so that an user system interface cable can
be connected. When designing the user system, refer to an example of recommended connection
between the connector and the MCU shown in this manual.
Before designing the user system, be sure to read the E10A-USB emulator user's manual and the
hardware manual for related MCUs.
Connect pins 8, 9, 10, 12, 13, and 14 of the user system connector to GND firmly on the PCB.
These pins are used as electrical GND and to monitor the connection of the user system connector.
Note the pin assignments of the user system connector.

Notes: 1. The pin number assignments of the 14-pin connector differ from those of the E8a
emulator; however, the physical location is the same.
2. When designing the connector layout on the user board, do not place any components
within 3 mm of the connector.
