AD7143
REGISTER MAP
The AD7143 address space is divided into three different
register banks, referred to as Bank 1, Bank 2, and Bank 3.
Figure 47 illustrates the division of these three 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 for
uniquely configuring the CIN 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 contains 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
AD7143 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.
