51<H2>Description</H2>
52<P>This function asynchronously compares the data of the FLASH device with the designated memory. This function immediately returns control. To use this function, you must first lock the access bus with the <A href="../backup/CARD_LockBackup.html"><CODE>CARD_LockBackup</CODE></A> function.</font> Use the <A href="../backup/CARD_WaitBackupAsync.html"><CODE>CARD_WaitBackupAsync</CODE></A> function to wait for processing to complete. To determine the processing result, call the <A href="../common/CARD_GetResultCode.html"><CODE>CARD_GetResultCode</CODE></A> function after processing is complete.<BR><BR> <font color="#800000">This function communicates with the ARM7 processor internally via PXI.<br> The process will not end if PXI interrupts are not enabled.<br></font> <br>
53</P>
54<h2>Internal Operation</h2>
55<p><CODE>The function uses an internal thread to execute an asynchronous process. See the description of the <A href="../common/CARD_GetThreadPriority.html"><CODE>CARD_GetThreadPriority</CODE></A> function for more information on this thread.</p>
