Description
When this bit is high, the contents of the data field will be written to the register specified by the Address
Field. When this bit is low, a read of the register specified by the Address Field will occur at the next
sample interval; the contents of the Data Field are ignored.
This 4-bit field is used to select one of the seven control registers of the AD74111.
This bit is reserved and should always be programmed with zero.
This 10-bit field holds the data that is to be written to or read from the register specified in the Address Field.
