+            Accessing memory in SPIRAM has certain restrictions, so task stacks allocated by xTaskCreate
+            are by default allocated from internal RAM.
+
+            This option allows for passing memory allocated from SPIRAM to be passed to xTaskCreateStatic.
+            This should only be used for tasks where the stack is never accessed while the cache is disabled.
