Y_OPEN_TRIG_
SEL R/W, Y_WIN_CON[19..16], Cyton-CXP
Selects which trigger will control the start Y wIndow.
Y_OPEN R/W, Y_WIN_CON[23..20], Cyton-CXP
This field specifies how the Y window starts. Possible values are: 0 - immediate mode,
1 - trigger mode.
If immediate mode is specified, no trigger synchronization is required. The acquisition
engine waits for any line sync requirements, opens the Y window, then starts the setup
of the X window.
If trigger mode is specified, the trigger is selected by Y_OPEN_TRIG_SEL and the con-
ditioning function is specified by Y_OPEN_TRIG_FUNC. The acquisition engine waits
for the trigger condition to be satisfied, opens the Y window, then starts the setup of
the X window.
Y_SYNC R/W, Y_WIN_CON[27..24], Cyton-CXP
This field enforces the data-synchronization of streaming video to the acquisition
engine for each individual line in the y window. The following table shows explains
this field.
Y_SYNC Meaning

after the Y Window are open will be acquired as part
of the current line.

dow.
