| 5 | Description: |
| 6 | Reading this file returns the stored CIR wakeup sequence. |
| 7 | It starts with a pulse, followed by a space, pulse etc. |
| 8 | All values are in microseconds. |
| 9 | The same format can be used to store a wakeup sequence |
| 10 | in the Nuvoton chip by writing to this file. |
| 11 | |
| 12 | Note: Some systems reset the stored wakeup sequence to a |
| 13 | factory default on each boot. On such systems store the |
| 14 | wakeup sequence in a file and set it on boot using e.g. |
| 15 | a udev rule. |
