; os_cpu_c.c 25 * INITIALISE A TASK'S STACK
; os_cpu_c.c 26 *
; os_cpu_c.c 27 * Description: This function is called by either OSTaskCreate() or OSTaskCreateExt() to initialise the
; os_cpu_c.c 28 * stack frame of the task being created. This function is highly processor specific.
; os_cpu_c.c 29 *
; os_cpu_c.c 30 * Arguments : task is a pointer to the task code
; os_cpu_c.c 31 *
; os_cpu_c.c 32 * pdata is a pointer to a user supplied data area that will be passed to the task
; os_cpu_c.c 33 * when the task first executes.
; os_cpu_c.c 34 *
; os_cpu_c.c 35 * ptos is a pointer to the top of stack. It is assumed that 'ptos' points to
; os_cpu_c.c 36 * a 'free' entry on the task stack. If OS_STK_GROWTH is set to 1 then
; os_cpu_c.c 37 * 'ptos' will contain the HIGHEST valid address of the stack. Similarly, if
; os_cpu_c.c 38 * OS_STK_GROWTH is set to 0, the 'ptos' will contains the LOWEST valid address
; os_cpu_c.c 39 * of the stack.
; os_cpu_c.c 40 *
; os_cpu_c.c 41 * opt specifies options that can be used to alter the behavior of OSTaskStkInit().
; os_cpu_c.c 42 *
; os_cpu_c.c 43 * Returns : Always returns the location of the new top-of-stack' once the processor registers have
; os_cpu_c.c 44 * been placed on the stack in the proper order.
; os_cpu_c.c 45 *
; os_cpu_c.c 46 * Note(s) : Interrupts are enabled when your task starts executing. You can change this by setting the
; os_cpu_c.c 47 * PSW to 0x0800 instead. In this case, interrupts would be disabled upon task startup. The
; os_cpu_c.c 48 * application code would be responsible for enabling interrupts at the beginning of the task
; os_cpu_c.c 49 * code. You will need to modify OSTaskIdle() and OSTaskStat() so that they enable
; os_cpu_c.c 50 * interrupts. Failure to do this will make your system crash!
; os_cpu_c.c 51 *
