However, the read operation is not added to the queue, so you need to wait if there is an ongoing flash operation on the same page to complete in order to be sure that the data is valid.</p> <p>One way to check if it&#39;s safe to read a block is to check that there are no pending flash operations by using the pstorage_access_status_get() function.</p><div style="clear:both;"></div>
