    Sector PFLASH

    Hello,

    I use a XMC 47 and want to write data into PFLASH.

    The Code I use:
    Code:
    XMC_FLASH_EraseSector(XMC_FLASH_SECTOR_11);
    XMC_FLASH_ProgramPage(XMC_FLASH_SECTOR_11, data);
    So I can write one page into Sector 11.

    What I have to do to write more pages into Sectro 11?


    Thanks for your help

    S.H.

    Code:
    /**
     *
     * @param address    Pointer to the starting address of flash page from where the programming starts.
     * @param data       Pointer to the source address where targeted data is located.
     *
     * @return None
     *
     * \par<b>Description:</b><br>
     * \if XMC1
     * Programs a single flash page associated with the specified \a address.\n\n XMC1000 Flash can be programmed with one
     * page (256 bytes) using this API. It calls the Flash Firmware routine \a XMC1000_NvmProgVerify(unsigned long pageAddr)
     * to perform the programming. Refer XMC1000 reference manual of for more details on flash firmware routines
     * (Section 25.3). Call XMC_FLASH_GetStatus() API after calling this API, to verify the programming operation.
     * \endif
     * \if XMC4
     * Programs a single flash page associated with the specified \a address.\n\n  XMC4000 flash can be programmed with a
     * granularity of 256 bytes page using this API. Before entering into page write process, it clears the error status
     * bits inside status register. It starts the write process by issuing the page mode command followed by the load page
     * command which loads the targeted \a data blocks into internal assembly buffer. Finally, it issues the write page
     * command which programs the \a data into flash. Call XMC_FLASH_GetStatus() API after calling this API, to verify the
     * programming operation.\n
     * \endif
     *
     * \par<b>Note:</b><br>
     * Flash will be busy state during write is ongoing, hence no operations allowed until it completes.
     *
     * \par<b>Related APIs:</b><BR>
     * None 
     *
