6.6.3 Address of the first pixel of a line
Register r4 defines the leftmost pixel. The value is the pixel address divided by ten.

Calculation of the value of r4:
Value of r4 = Pixel-Nr./10

Calculation of the value of r5:
Value of r5 = Pixel-Nr./10

The difference r5 - r4 must be in the range: 0
≤
r5-r4
≤
7fh .
6.6.5 Tracking
For rapid window movement even at slow baud rates a short command is provided..
command:
:t<n>,<m>
<m>
= X-position in pixel/10,
range 00h ...07fh
<n>
= Y-position in lines / 4,
range 00h ...0ffh
Response:
none
6.6.6 Arbitrary shaped fields of view
Standard adjustment of the camera using the parameters
address of 1. pixel in a line
,
address of last
pixel in a line
,
address of first line
and
number of lines
only allows to define one rectangular window .
For more than one window MC13xx offers a separate function, which allows to select more fields of
iew with different shapes.
It can be adjusted by a selection mask consisting of 16.384 read tiles. Each tile has a size of 10(H) x
8(V). All 16.384 tiles cover the whole active sensor area.
The selected tiles are summed up in 2.048 selection bytes with 8 bit and can be loaded sequentially via
register r8. Each set bit in a selection byte causes the associated tile to be captured and read out.
