RTEMS (Real-Time Executive for Multiprocessor Systems) is a free open source real-time operating sys

/*  Task_1
 *
 *  This routine serves as a test task.  It establishes an RTEMS_ASR and
 *  sends signal to itself to determine if the RTEMS_ASR gets to execute.

 *  Input parameters:
 *    argument - task argument

 *  Output parameters:  NONE
