Functional Description
3.2
In interlaced readout mode, pixels are read out in two fields, an
Odd Field followed by an Even Field.
The Odd Field, consisting of all odd row pairs contained within
the display window, is read out first. Each pixel in the “Odd Field”
is consecutively read out, one pixel at a time, starting with the
top left most pixel.
The Even Field, consisting of all even row pairs contained within
the display window, is then read out. Each pixel in the “Even
Field” is consecutively read out, one pixel at a time, starting with
the top left most pixel.

Note b:
The following are examples of how programming different scan
window sizes effect the interlace read out:
Example 1, figure 14 shows a “Scan Window” of 20 rows and a
“Display Window” of 20 rows and 18 columns. This is broken up
into two fields:
• The odd field is read out first. The odd field will consist of pix-
• The even field is then read out. The even field will consist of

When using a color sensor in interlace mode, the
ScanMode bit in the MCFG1 register should be set to
a logic one.
If a Scan Window is defined with an odd number of
rows, the timing and control circuit will automatically
append an additional row. The is only true when the
ScanMode bit in the MCFG1 register is set to a logic
one.

Example 2, figure 15 shows an interlace read out when a “Scan
Window” of 5 or 6 rows and a “Display Window” of 5 or 6 row
and 18 columns is programmed.
Example 3, figure 16 shows an interlace readout when a “Scan
Window” of 9 or 10 rows and a “Display Window” of 9 or 10 row
and 18 columns is programmed.
Example 4, Figure shows an interlace readout when a “Scan
Window” of 3 or 4 rows and a “Display Window” of 3 or 4 row
and 18 columns is programmed.
