7. Function Descriptions
Figure 12 is a general outline of the functions on the evaluation board. The board is equipped with an R8C/34K Group
MCU and provides these functions using the MCU peripheral functions with the on-board circuits listed in
Table 1
.
Each function is described in detail below. For details concerning the MCU functions, memory map, etc., refer to the
R8C/34U Group, R8C/34K Group User’s Manual: Hardware.

Evaluation Board General Function Outline
7.1 USB Function (Red dot line area of Figure 12)
The evaluation board is equipped with a USB Standard A receptacle and a host power supply (VBUS) control IC to
enable use of the MCU USB Host function.
JP3 must be fixed to “HOST” position.
7.2 RS232C Transmission (Green dot line area of Figure 12)
The evaluation board is equipped with the RS232C transmission function, which uses the MCU UART0, and a D-sub9
pin male connector (CN5). Use a “cross through cable” when connecting the emulator to your computer.
