.. rubric:: CONSTRAINTS:
|
|
|
|
The following constraints apply to this directive:
|
|
|
|
* The directive may be called from within interrupt context.
|
|
|
|
* The directive may be called from within device driver initialization context.
|
|
|
|
* The directive may be called from within task context.
