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, every n
th
line
is omitted. 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 shutter 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 Regis-
ter rB
h
[6..0]. This is called the release condition.
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.
