# CARD_WriteAndVerifyFram

## C Specification

  `#include <nitro/card.h>`
  `static inline BOOL CARD_WriteAndVerifyFram(u32 dst, const void *src, u32 len);`

## Arguments

dst | Transfer destination FRAM address.
src | Transfer source memory address.
len | Byte length of data being written.

## Return Values

TRUE if the process succeeds and the data are the same. FALSE otherwise.

## Description

Writes data to the FRAM device and compares the written data. The function does not return control until it has finished processing. If the process succeeds and the data matches, the function returns TRUE. Otherwise, it returns FALSE. 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.

## Internal Operation

This function communicates with the ARM7 processor internally via PXI.
The process will not end if PXI interrupts are not enabled.
