7.1.4.3 USB Interface Function Switching
The microcontroller has the following two USB interface functions, which can be switched
by external jumper socket.
（１） USB Host Interface Function
（２） USB Function Interface Function
This section contains an overview of the two interface functions and a description of the
setting method.
（１） USB Host Interface Function (Set when User Mode is Selected)
[Overview]
The USB interface of the microcontroller is used as the host.
[Setting Method]
Insert the jumper for switching modes of the microcontroller in the silk notation “HOST” side.
Figure 31 USB Host Function Setting Method
（２） USB Function Interface Function (Set when Serial Writer Mode is Selected)
[Overview]
The USB interface of the microcontroller is used as the function.
[Setting Method]
Insert the jumper for switching modes of the microcontroller in the silk notation “DEV” side.
