Register Address Banks 1 and 2
The AD9995 address space is divided into two different regis-
ter banks, referred to as Register Bank 1 and Register Bank 2.
Figure 41 illustrates how the two banks are divided. Register
Bank 1 contains the registers for the AFE, miscellaneous func-
tions, VD/HD parameters, timing core, CLPOB masking, VSG
patterns, and shutter functions. Register Bank 2 contains all
of the information for the V-pattern groups, V-sequences, and
field information.

WRITE TO ADDRESS 0x7F TO SWITCH REGISTER BANKS
–38–
When writing to the AD9995, Address 0x7F is used to specify
which address bank is being written to. To write to Bank 1, the
LSB of Address 0x7F should be set to 0; to write to Bank 2, the
LSB of Address 0x7F should be set to 1.
Note that Register Bank 1 contains many unused addresses. Any
undefined addresses between 0x00 and 0x7F are considered
don’t cares, and it is acceptable if these addresses are filled in
with all 0s during a continuous register write operation. However,
the undefined addresses above 0x7F must not be written to, or
the AD9995 may not operate properly.
