DS110DF410: 0XFF Register

Part Number: DS110DF410

Hi

As DS110DF410 datasheet says, 0XFF readback will yield an invalid value. Then how we could verify if we write 0XFF successfully? Thanks!

Regards

    Hi David,

    If you are unsure you are correctly writing to the register 0xFF it is possible to use a channel register like 0x5F.  By writing independent values into this register location in each channel, it would be possible to verify that 0xFF is being accessed as expected.  Another method would be to adjust the VOD values for each channel and use an oscilloscope to verify the VOD adjustments.

    In addition, control registers 0x00 and 0x01 contain the SMBus address and device ID to verify that you are reading from the expected location. 

    Regards,
