Complete Field: Combining the Regions
The individual regions are combined into a complete field readout
by using region change positions (RCP) and region pointers
(REGPTR). Figure 22 shows how each field is divided into
multiple regions. This allows the user to change the vertical
timing during various stages of the image readout. The boundaries
of each region are defined by the sequence change positions
(RCP). Each RCP is a 12-bit value representing the line number
bounding the region. A total of seven RCPs allow up to eight

different region areas in the field to be defined. The first RCP is
always hard-coded to zero, and the remaining seven are register
programmable. Note that there are only five possible individual
regions that can be defined, but the eight region areas allow the
same region to be used in more than one place during the field.
Within each region area, the region pointers specify which of the
five individual regions will be used. There are eight region
pointers, one for each region area. Table IX summarizes the
registers for the region change positions and region pointers.
