The KitProg3 user interface is limited to one or two mode switches and one or three status LEDs, depending upon the kit. The name and location of the mode switch(es) vary per kit. See the kit documentation to understand what switches and LEDs on the kit are used for KitProg3. See

Mode Switching

for information on how to use the mode switches.

The following table describes how KitProg3 uses LEDs to let you know what's going on. In CMSIS-DAP Bulk and CMSIS-DAP HID modes, green means success and red means there was a problem. In DAPLink mode the green LED flashes when the USB MSC interface is active, the red LED flashes when USB CDC interface is active.
