## Description

This function writes data to the FRAM device. The function does not return control until it has finished processing. It returns TRUE if the process was successful or FALSE if it failed. To get the detailed result value when the process fails, call the `CARD_GetResultCode` function. In order to use this function, you must first lock the access bus with the `CARD_LockBackup` function.
This function communicates with the ARM7 processor internally via PXI.
The process will not end if PXI interrupts are not enabled.
