3. Notes on Usage
Note on Power-Supply Voltage:
When you use an emulator with this isolator connected, power-supply voltage of the MCU on your
system should be between 3.0 V and 5.5 V. Power-supply voltage less than 3.0 V is not supported
Power-supply voltage less than 3.0 V is not supported.
Note on Signal Delay:
When this product is connected, the communication interface speed may be limited due to the signal
delay of the isolation circuit.
Use the e
2
studio as the debugger.
Set the e
2
studio communication speed to "AUTO". (The connection speed is optimal.)
The e
2
studio must be version 2021-10 (21.10.0) or higher.
Note on Programming Software:
Use the Renesas Flash Programmer as the writing software.
If you are unable to start the Renesas Flash Programmer, run e
2
studio once.
4. Usage
Sections 4.1 to 4.3 of this chapter use the E2 Emulator as an example. If you are using the E2 emulator Lite,
read "E2 Emulator" as "E2 emulator Lite". Set the jumper pins according to the usage before connecting.
(See Chapter 5)
