2. Usage Environment
This section provides the circuit diagram and operating environment of the hardware on which this sample program is
to run.
2.1 Circuit Diagram
See “V850E2/MN4 Target Board User Manual: QB-V850E2MN4DUAL-TB (R20UT0683XJ)” for the details of the
circuit diagram.
This sample program performs serial communication between the UARTJ1 and the UARTJ3. The UARTJ1 transmits
data and the UARTJ3 receives the data. The P13_4 pin and the P13_5 pin are used for the TXD1F pin and the RXD1F
pin for the UARTJ1, respectively. The P4_6 pin and the P4_7 pin are used for the TXD3F pin and the RXD3F pin for
the UARTJ3, respectively. The TXD1F pin is connected to the RXD1F pin and the RXD1F pin is connected to the
TXD3F pin.
LED1 and LED2 are connected to port 13. The P13_7 pin is used for LED1. The P13_6 pin is used for LED2.
2.2 Development Environment
It is necessary to install the tools that are listed below to run the sample program.
• CubeSuite+
The integrated development environment CubeSuite+ from Renesas Electronics provides various software
development tools that are necessary for the user to develop applications. The user can use these tools seamlessly
and easily in various development stages including coding, assembly, compilation, debugging using an emulator or
simulator, and flash programming.
• MINICUBE
MINICUBE is a general-purpose in-circuit emulator from Renesas Electronics which adopts the JTAG interface
system. It allows the user to debug an onboard real processor and provides highly transparent and stable emulation
functionalities. An adapter is required to connect a TB board to MINICUBE.
