PIC32MM写入擦除NMV故障

嗨，所有，我使用PIC32 MM000 64 GPL028设备与2.6V电源。尝试写双字写后，我读通过皮卡3 0X…4800 - DFFFFFFF FFFFF 6dB值。值更改但不正确。我尝试用代码从600 01121G.PDF AppNoT和在调试器中检查调试器的正确值，值正确，但结果是错误的。现在我不明白怎么回事。一切看起来都像是在工作。明天我将尝试使用Pig32 mm PIB模块使用Explorer 16/32板进行测试。

    Hi All,

I used PIC32MM0064GPL028 device with 2.6V power.

Try wrote double word


       uint32_t data_h, data_l, lc_addr;

       lc_addr = 0x1D004800;

       __builtin_disable_interrupts();

        data_h = 0x00000000;
        data_l = 0x11111111;

        NVMDATA0 = data_l;
        NVMDATA1 = data_h;

        NVMADDR = lc_addr;
        
        NVMCON = 0;
        NVMCONbits.NVMOP = 2;
        NVMCONbits.WREN = 1;
        
        NVMKEY = 0x0;
        NVMKEY = 0xAA996655;
        NVMKEY = 0x556699AA;

        NVMCONbits.WR = 1;

        while (NVMCONbits.WR);

        NVMCONbits.WREN = 0;
        
        res = NVMCON;
        if (res & 0x3000) {
            ret = 1;
        }

        __builtin_enable_interrupts();


After writing I read via PicKit 3 0x...4800 - DFFFFFFF FFFFF6DB values. Values changed but incorrect.
I try a lot of test with code from 60001121g.pdf AppNote and check by debugger correct values in regs,
values writed correct but result is wrong.

Now I don't understand what's wrong. All looking as working. Tomorrow I'll try do some tests with Explorer 16/32 board with PIC32MM PIB module.
