AD7175-2 digital interface check

Q: I’m not sure if my digital interface is working on AD7175-2  – how can I check this?

A: The ADC has a read-only ID register which will always read back as 0x0CDx.

    Hi Maurooven,

         The X is not unique per unit and it  is a number to complete the ID register which is a read only.

    In the page 48 of manual the register nr. 0x07 containing the ID states the number you find reading this register is x0CDx, in the manual is also written as 0x0CDX. I would assume the last "X" stands for hexadecimal code but

    other codes when listing the Reset's default values don't have this postfix "X"; for example the register 0x20 report as Reset's value: 0x1320.

    Is the "X" of the 0x0CDX a number which is unknown or variable from unit to unit?

    Is the 0x0CDX number = to 0xCD ?

    Actually my read is = 0xCDE ... = binary 0000 1100 1101 1110

    Has the datasheet to be updated or the E i get here can change from device to device?
