See Table V.
This location will contain the company identification number. This
register is read only.
This location will contain the revision number of the part in the lower
four bits of the register [3:0]. The upper four bits reflect the ADM1022
Version Number [7:4]. The first version is 1100. The next version of
ADM1022 would be 1101, etc. For instance, if the stepping were A0
and this part is an ADM1022, this register would read 1100 0000.
This register is read only.
