+ * register word sizes. This means that whatever variable we
+ * pass _must_ be a multiple of 32 bits. Otherwise the device
+ * might not accept what we are sending to it.
+ * This will also make it easier for the driver to write
+ * the data to the device.
+ *
+ * Also note that when NULL is passed as address the
