| * - Led 0 is on when USB line is in IDLE mode, and off in SUSPEND mode | |
| * - Led 1 blinks when USB Host have checked and enabled HID generic interface | |
| * - Led 4 to 7 are controlled by USB Host application | |
| * - Switch 0 events are reported to USB Host application | |
| * - Switch 0 can be used to wakeup USB Host in remote wakeup mode. | |
