COMPLETE FIELD—COMBINING H-PATTERNS
After creating the H-patterns, they combine to create different
readout fields. A field consists of up to nine different regions
determined by the SCP registers, and within each region, a
different H-pattern group can be selected, up to a maximum of
32 groups. Registers to control the H-patterns are located in the
field registers. Table 13 describes the field registers.

FIELD SETTINGS:
1. SEQUENCE CHANGE POSITIONS (SCP0 TO SCP8) DEFINE EACH OF THE NINE AVAILABLE REGIONS IN THE FIELD.
2. HPAT_SEL SELECTS THE DESIRED H-PATTERN FOR EACH REGION.

H-Pattern Selection
The H-patterns are stored in the HPAT memory, as described in
Table 33. The user decides how many H-pattern groups are
required, up to a maximum of 32, and then uses the HPAT_SELx
registers to select which H-pattern group is output in each
region of the field. Figure 32 shows how to use the HPAT_SELx
and SCPx registers. The SCPx registers create the line
boundaries for each region.
