Notes:
1
The circuits and resistance values listed are recommended but not guaranteed. Determine the circuit
design and resistance values by taking into account the specifications of the target device and noise.
For flash programming for mass production, perform sufficient evaluation about whether the
specifications of the target device are satisfied.
2
For processing of pins not used by the E1/E20/E2/E2 Lite, refer to the hardware manual for the
device.
3
For details on how to handle the RESET# pin, refer to section 2.5, Notes on Connection.
4
The RESET_IN pin is used only in debugging. The emulator operates for flash programming by the
programming software whether this pin is connected or not.
5
The driving power supply for the TOOL0 pin is different depending on devices. Refer to the
user’s
manual for the device.
Please connect VDD when the MCU does not have power supplies other than VDD such as EVDD.
6
Securely connect pins 2, 12, and 14 of the connection to GND of the user system. These pins are
used for electrical grounding as well as for monitoring of connection with the user system by the
E1/E20/E2/E2 Lite.
7
Securely connect both pin 10 and pin 13.
8
When you use hot plug-in, install a ceramic capacitor (approx. 0.1 µF) between the RESET# pin and
GND in order to suppress a noise to the RESET# pin that would occur when the emulator is
connected.
