REGISTER MAP
The AD7147 address space is divided into three register banks,
referred to as Bank 1, Bank 2, and Bank 3. Figure 62 illustrates
the division of these banks.
Bank 1 registers contain control registers, CDC conversion
control registers, interrupt enable registers, interrupt status
registers, CDC 16-bit conversion data registers, device ID
registers, and proximity status registers.
Bank 2 registers contain the configuration registers used to
configure the individual CINx inputs for each conversion stage.
Initialize the Bank 2 configuration registers immediately after
power-up to obtain valid CDC conversion result data.

Bank 3 registers contain the results of each conversion stage.
These registers automatically update at the end of each conversion
sequence. Although these registers are primarily used by the
AD7147 internal data processing, they are accessible by the host
processor for additional external data processing, if desired.
Default values are undefined for Bank 2 registers and Bank 3
registers until after power-up and configuration of the Bank 2
registers.
