    #define IAPENTRY ((IAP) 0x7FFFFFF1)
    struct iap_in { unsigned int cmd; unsigned int par[4];
    };
    struct iap_in sIapInput;

    int main()
    { char a[512];
    unsigned long flash_addr = 0x4000;
    int size = 256;
    for(i=0;i<512;i++)
    a[i]=i;

    sIapInput.cmd = 51;
    sIapInput.par[0] = (unsigned int) flash_addr;
    sIapInput.par[1] = (unsigned int) data;
    sIapInput.par[2] = size; sIapInput.par[3] = CCLK; IAPENTRY(&sIapInput, uiResult);
    }
