SeqMode description
Sequence repeat counter (new for 3.x)
For each parameter set one can define an image repeat counter. Using the
image repeat counter means that a parameter set can be used for n consecutive
images before the next parameter set is applied.
Setting the ImageRepeat field to 0 has the same effect like setting this field to
1.
Manual stepping & reset (new for 3.x)
With firmware 3.x a sequence can be stepped further with a software command.
To use manual stepping use stepping mode 0x82 or 0x84, but do not setup any
input pin for external sequence stepping.
Every time the PerformStep flag is set the sequence will be stepped one param-
eter set further. Manual stepping observes the repeat counter also.
For some application it could be useful to reset the sequence during runtime.
Simply set the PerformReset flag to one: the sequence starts over with the very
first parameter set.
Sequence mode
Description
0x80
This mode is the default sequence mode and stepping the
sequence is compatible to e.g. the Marlin series. With
each image integration start the sequence is stepped one
item further and the new parameter set becomes active for
the next image.
0x82
Stepping of the sequence is controlled by a rising edge of
an external signal. The new parameter set becomes active
with the next integration start. When using this mode
select the suitable input mode of the input lines.
0x84
Stepping of the sequence is controlled by a high level of
an external signal. The new parameter set becomes active
with the next integration start. When using this mode
select the suitable input mode of the input lines.
Other mode
Choosing any other mode value, automatically defaults to
mode 0x80.

Note
It is also possible, that a sequence consists of parameter sets
with different sequence modes. This can be achieved by using
the SeqMode and the ImageNo fields within the
Sequence_Param register.
