| * Human interface on Xplain-A1: | |
| * - RED led close to USB connector is always on after firmware startup | |
| * - The led 0 is on when CPU is not in power down mode, | |
| * and the power down mode is enabled when a suspend mode is detected on USB line | |
| * - The led 1 blinks when USB Host have checked and enabled CDC interface | |
| * - The led 2 is on when CDC port is open | |
| * - The led 4 is on during data transfer from CDC to UART | |
| * - The led 5 is on during data transfer from UART to CDC | |
| * - The led 6 signals an frame error on UART | |
| * - The led 7 signals an overflow | |
