Notes: 1. These are the names of the MCU pins at the time the E2/E2 Lite is connected (i.e. during
debugging).
2. Input to or output from the user system.
3. Securely connect pins 3, 5, 9, 15, 17, and 19 of the connector to GND on the user system.
These pins are used for electrical grounding as well as for monitoring of connection with the
user system by the E2/E2 Lite.
4. If a 10-pin (1.27-mm pin pitch) connector is mounted on the user system, pins 11 to 20 are
not used.
