|

*
|

* 1. One limitation in the use of NXFLAT is that functions that are

* referenced as a pointer-to-a-function must have global scope.
|

* Otherwise ARM GCC will generate some bad logic.
|
||||
* 2. In general, when called back, there is no guarantee to that PIC

* registers will be valid and, unless you take special precautions, it
|

* could be dangerous to reference global variables in the callback
