140 * INITIALIZE A TASK'S STACK
141 *
142 * Description: This function is called by either OSTaskCreate() or OSTaskCreateExt() to initialize the
143 * stack frame of the task being created. This function is highly processor specific.
144 *
145 * Arguments : task is a pointer to the task code
146 *
147 * os_pdata is a pointer to a user supplied data area that will be passed to the task
148 * when the task first executes.
149 *
150 * ptos is a pointer to the top of stack. It is assumed that 'ptos' points to
151 * a 'free' entry on the task stack. If OS_STK_GROWTH is set to 1 then
152 * 'ptos' will contain the HIGHEST valid address of the stack. Similarly, if
153 * OS_STK_GROWTH is set to 0, the 'ptos' will contains the LOWEST valid address
154 * of the stack.
155 *
156 * opt specifies options that can be used to alter the behavior of OSTaskStkInit().
157 * (see uCOS_II.H for OS_TASK_OPT_???).
158 *
159 * Returns : Always returns the location of the new top-of-stack' once the processor registers have
160 * been placed on the stack in the proper order.
161 *
162 * Note(s) : Interrupts are enabled when your task starts executing. You can change this by setting the
163 * PSW to 0x0002 instead. In this case, interrupts would be disabled upon task startup. The
164 * application code would be responsible for enabling interrupts at the beginning of the task
165 * code. You will need to modify OSTaskIdle() and OSTaskStat() so that they enable
166 * interrupts. Failure to do this will make your system crash!
