Dear  ALL
    I have read the <Programmer’s Guide DS160PR412, DS160PR421 Programming Guide>

  Now I can use I2C to read the DS160PR412 register . but I want to write these register I find the always is not change . i have a detail timing about the I2C  for  DS160PR412, DS160PR421. can you share a file to me .

  For example  i have  DS160PR412  and  DS160PR421  in one baord. 

 First i read the share register . I can read it . 
[BANK0]LMH_412_i2c_read REG[0xF1]=27 
[BANK0]LMH_412_i2c_read REG[0xF0]=1A 
[BANK0]LMH_412_i2c_read REG[0xF1]=27 
[BANK0]LMH_421_i2c_read REG[0xF1]=27 
[BANK0]LMH_421_i2c_read REG[0xF0]=1E 
[BANK0]LMH_421_i2c_read REG[0xF1]=27 
[BANK0]LMH_421_i2c_read REG[0xF0]=1F 

Now if I want to  
LMH_412_i2c_write(LHM_412_BANK0_ADDR,0x0E,0x04);
 LMH_412_i2c_write(LHM_412_BANK0_ADDR,0x0F,0x04);
and then I read these register . the value is not change . 

So  pls tell me timing hwo to write the register thanks. for example Write Mask how to tell the chip
