(0133) * INITIALIZE A TASK'S STACK
(0134) *
(0135) * Description: This function is called by either OSTaskCreate() or OSTaskCreateExt() to initialize the
(0136) * stack frame of the task being created. This function is highly processor specific.
(0137) *
(0138) * Arguments : task is a pointer to the task code
(0139) *
(0140) * p_arg is a pointer to a user supplied data area that will be passed to the task
(0141) * when the task first executes.
(0142) *
(0143) * ptos is a pointer to the top of stack. It is assumed that 'ptos' points to the
(0144) * highest valid address on the stack.
(0145) *
(0146) * opt specifies options that can be used to alter the behavior of OSTaskStkInit().
(0147) * (see uCOS_II.H for OS_TASK_OPT_???).
(0148) *
(0149) * Returns : Always returns the location of the new top-of-stack' once the processor registers have
(0150) * been placed on the stack in the proper order.
(0151) *
(0152) * Note(s) : Interrupts are enabled when your task starts executing. You can change this by setting the
(0153) * SREG to 0x00 instead. In this case, interrupts would be disabled upon task startup. The
(0154) * application code would be responsible for enabling interrupts at the beginning of the task
(0155) * code. You will need to modify OSTaskIdle() and OSTaskStat() so that they enable interrupts.
(0156) * Failure to do this will make your system crash!
(0157) *
(0158) * The AVR return stack is placed OS_TASK_HARD_STK_SIZE bytes before the bottom of the task's
(0159) * stack.
(0160) *
(0161) * (1) IMPORTANT: The ICC compiler handles function pointers by actually passing the pointer
(0162) * to a location in Flash that actually contains the pointer to the function.
