USB connector (CN4)
This connector is connected to a USB-Serial transfer IC, and is recognized as a virtual
COM port by a PC.
Please download a USB driver from below URL.
URL： http://www.ftdichip.com/
Usually, the USB driver is install automatically on Windows PC.
You can use a virtual COM port as general purpose UART or serial programming with SCI
boot mode.
Set JP13 short-pin close.

When you do the serial programming with the SCI boot mode, set the short-pin below.
Do not connect emulator to SWD I/F(CN1) when using with SCI boot mode.
When you make the serial communication by UART, set the short-pin below.
Do not connect anything to PmodTM connecter(CN3、CN7) when you use a UART.
PmodTM connecter（CN3）
This connector is a Digilent PmodTM compatible connector as the 12pin SPI connection.
When you use this connecter, set JP10, JP11 OPEN and do not connect anything to
