6.18.4 ImageBLITZ® setup
The MC13xx is configured for asynchronous operation with timer , registers r8, r9 and rC
h
are loaded
for the desired position of the trigger line. Register rB
h
is loaded with 0, register rA
h
with 201
h,
so that
the trigger line is visible.
L
If the image is zoomed down for display by an applica-
tion program, every other line may be omitted and the
trigger line may then disappear.
ImageBLITZ® is enabled with Register r7 Bit1=1.
Now position the trigger line with the registers r8, r9 and rC
h
across the object that is used for the shut-
ter release..
Clear Bit 8 in Register rA
h
if a bright objects releases the shutter, set rA
h
[8] if dark objects release the
shutter. While the trigger line is placed across the object, raise threshold with rA
h
[7..0] until as many
dashes from the trigger line disappear as are loaded in Register rB
h
[6..0]. This is called the release con-
dition.
If it is expected that the release condition is met more than once for a single object, load rB
h
[9..7] with
a number of exposed lines that will not met the release condition before exposing one image.
