UART Connector
The Evaluation Board has through holes for CN_UART connector and test points (TP_UART) to confirm the
UART signals. The UART is also used for the connection circuit with the motor control development support
tool Renesas Motor Workbench through ICS_SEL jumpers, so when using the CN_UART connector, change
all ICS_SEL jumpers to open. The CN_UART connector is not used in the sample program.
