| NOTE: ata_idle_nofity usage notes.. |
| |
| 1) the callbacks are called in the ata thread, not main/your thread. |
| 2) Asyncronous callbacks (like the buffer refill) should be avoided. |
| If you must use an async callback, remember to check ata_is_active() before |
| accessing the disk, and nonot call any functions between that check and the |
| disk access which may cause a yield (lcd_update() does this!) |
| 3) Do not call cany yielding functions in the callback |
| 4) Do not call ata_sleep in the callbacks |
| 5) Dont Panic! |
