51<H2>Description</H2>
52<P>Writes data asynchronously to an EEPROM device. 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 end. 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>
56This function executes an asynchronous process using an internal thread. See the description of the <A href="../common/CARD_GetThreadPriority.html"><CODE>CARD_GetThreadPriority</CODE></A> function for more information on this thread.
