Horizontal Sequence Control
The AD9848/AD9849 uses Sequence Change Positions (SCP)
and Sequence Pointers (SPTR) to organize the individual horizon-
tal sequences. Up to four SCPs are available to divide the
readout into four separate regions, as shown in Figure 12.
The SCP 0 is always hard-coded to line 0, and SCP1–3 are regis-
ter programmable. During each region bounded by the SCP, the
SPTR registers designate which sequence is used by each signal.

CLPOB, CLPDM, PBLK, and HBLK each have a separate
set of SCP. For example, CLPOBSCP1 will define Region 0
for CLPOB, and in that region any of the four individual
CLPOB sequences may be selected with the CLPOBSPTR
registers. The next SCP defines a new region, and in that
region each signal can be assigned to a different individual
sequence. The Sequence Control Registers are summarized
in Table VI.
