|
*
|
||
|
|
* I went through these registers to see which ones were actually required to make the thing work.
|
||
|
|
* It wasn't very many.
|
||
|
|
* This does sort of screw with the accuracy of the proximity detection,
|
||
|
|
* I think that's somewhere at the start of bank 1.
|
||
|
|
* There may be other stuff this screws with that I'm not testing.
|
||
|
|
*
|
||
|
|
* Notably, though, a lot of these values were the defaults specified in the datasheet.
|
||
|
|
* I think somebody just copied everything over and nobody's ever bothered to check what's actually needed.
|
||
|
|
* Well, I'm almost out of RAM, so I checked.
