/* NOTEs:
|
|
*
|
|
* 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 function.
