Notes: 1. Securely connect pins 2, 12, and 14 of the connector to GND of the user system. These pins are used for
electrical GND and to monitor connection with the user system by the E2 emulator.
2. The EVTO pin provides for the output of event signals from the device to the E2 emulator. Although
connecting the EVTO pin is not essential, we recommend connecting this pin in advance.
In some devices, the EVTO pin is not present or is only available as a pin function multiplexed with other
functions. When the EVTO pin is a multiplexed pin function and the event output function is to be used, set the
EVTO pin so that it will function as the EVTO pin by making the required register settings described in the
user's manual for the device.
3. Input and output are defined from the perspective of the target device.
Unused pins:
Do not apply signals from the user system to unused pins. Doing so may damage the pins.
