    Solved by myself
    1.Set register a0 to the base address of the NVM register (0xBF80_0600).
    XferInstruction (32'h3c04bf80).
    XferInstruction (32'h34840600).
    2. Set the NVMDATAx register 
    XferInstruction (0x3c10<data31:16> ).  //lui s0, <DATA(31:16)>
    XferInstruction (0x3610<data15:00>). //ori s0,s0,<DATA(15:0)>
    XferInstruction (ac9000<offset).  ///sw s0,offset(a0) 
     
    Note:  NVMDATA0:NVMDATA1:NVMDATA2:NVMDATA3 Registet offset :=30/ 40/ 50 /60
