; * INITIALIZE A TASK'S STACK
; *
; * Description: This function is called by either OSTaskCreate() or OSTaskCreateExt() to initialize the

; *
; * Arguments : task is a pointer to the task code
; *
; * os_pdata is a pointer to a user supplied data area that will be passed to the task
; * when the task first executes.
; *
; * ptos is a pointer to the top of stack. It is assumed that 'ptos' points to
; * a 'free' entry on the task stack. If OS_STK_GROWTH is set to 1 then
; * 'ptos' will contain the HIGHEST valid address of the stack. Similarly, if
; * OS_STK_GROWTH is set to 0, the 'ptos' will contains the LOWEST valid address
; * of the stack.
; *
; * opt specifies options that can be used to alter the behavior of OSTaskStkInit().
; * (see uCOS_II.H for OS_TASK_OPT_???).
; *
; * Returns : Always returns the location of the new top-of-stack' once the processor registers have
