6.2 USB High Speed
The USB Micro-AB connection jack (J31) connects the RA MCU USB High Speed interface to an external
USB interface, allowing communications for testing and use of the RA MCU firmware. This connection can
be configured as either a USB Device or a USB Host interface.
For a USB Device configuration, set Jumper J7 to pins 2-3, install a jumper on J17 pins 1-2, and configure
the RA MCU firmware to use the USB High Speed ports in Device mode. Power from an external USB Host
on this connection can be used to provide power to the EK-RA6M5 board.
For a USB Host configuration, set Jumper J7 to pins 1-2, remove the jumper from J17, and configure the RA
MCU firmware to use the USB High Speed ports in Host mode. In this configuration, power to J7 is supplied
from U5. The total current available from U5 is 500 mA. Note that the input power sources must be
configured with enough power for both the EK-RA6M5 board and the USB Full Speed port in Host mode.
Connect the included USB Type-A female to micro-B male cable to J31. USB device cables or devices can
be connected to the USB High Speed port using this cable.
