* The DMA stuff is not complete, only "normal" transfers are working |
8 |
|
|
* (source and destination addresses incrementing). |
9 |
|
|
* |
10 |
|
|
* Also, these transfers are "instantaneous" from a CPU point-of-view: when |
11 |
|
|
* a channel is enabled, the transfer is immediately done. So, this is not |
12 |
|
|
* very realistic. |
