LAYOUT OF INTERNAL REGISTERS
The AD9992 address space is divided into two register areas, as
illustrated in Figure 85. In the first address space, Address 0x00
to Address 0xFF contain the registers for the AFE, miscellaneous,
VD/HD, I/O and CP, timing core, shutter and GPO, mode, and
update control functions. The second address space, beginning
at Address 0x800, consists of the V-pattern groups, V-sequences,
and field registers. This is a configurable set of registers; the user
can decide how many V-pattern groups, V-sequences, and fields
are used in a particular design. Therefore, the addresses for
these registers vary, depending on the number of V-patterns
and V-sequences chosen.
Address 0x28 specifies the total number of V-pattern groups
and V-sequences used. The starting address for the V-pattern
groups is always 0x800. The starting address for the V-sequences
is based on the number of V-pattern groups used, with each
V-pattern group occupying 48 register addresses. The starting
address for the field registers depends on both the number of
V-pattern groups and the number of V-sequences. Each V-
sequence occupies 40 register addresses, and each field occupies
16 register addresses.
The starting address for the V-sequences is equal to 0x800 plus
the number of V-pattern groups times 48. The starting address
for the fields is equal to the starting address of the V-sequences
plus the number of V-sequences times 40. The V-pattern,
V-sequence and field registers must always occupy a continuous
block of addresses.
Figure 86 shows an example in which three V-pattern groups,
four V-sequences, and two fields are used. The starting address
for the V-pattern groups is always 0x800. Because VPATNUM = 3,
the V-pattern groups occupies 144 address locations. The start of
the V-sequence registers is 0x890 (that is, 0x800 + 144). With
VSEQNUM = 4, the V-sequences occupy 160 address locations.
Therefore, the field registers begin at 0x930 (that is, 0x890 + 160).
The AD9992 address space contains many unused addresses.
Undefined addresses between Address 0x00 and Address 0xFF
should not be written to; otherwise, the AD9992 may operate
incorrectly. Continuous register writes should be performed
carefully so that undefined registers are not written to.
