+ * reached (for example after exit()).
+ *
+ * The first action of this function is to call the fatal handler of the user
+ * extensions.  For the initial extensions the following conditions are
+ * required
+ * - a valid stack pointer and enough stack space,
+ * - a valid code memory, and
+ * - valid read-only data.
+ *
+ * For the initial extensions the read-write data (including BSS segment) is
+ * not required on single processor configurations.  On SMP configurations
+ * however the read-write data must be initialized since this function must
+ * determine the state of the other processors and request them to shut-down if
+ * necessary.
+ *
+ * Non-initial extensions require in addition valid read-write data.  The BSP
+ * may install an initial extension that performs a system reset.  In this case
+ * the non-initial extensions will be not called.
+ *
+ * Once all fatal handler executed the error information will be stored to
+ * _Internal_errors_What_happened and the system state is set to
+ * SYSTEM_STATE_TERMINATED.
+ *
+ * The final step is to call the CPU specific _CPU_Fatal_halt().
+ *
