off positions. STROBON_FD is the field in which the STROBE
is turned on, measured from the field containing the last SUBCK
before exposure begins. The STROBON_ LN PX register gives
the line and pixel positions with respect to STROBON_FD. The
STROBE off position is programmable to any field, line, and
pixel location with respect to the field of the last SUBCK.
TRIGGER Register Limitations
While the TRIGGER register can be used to perform a complete
exposure and readout operation, there are limitations on its use.
Once an exposure-plus-readout operation has been triggered,
another exposure/readout operation cannot be triggered right
away. There must be at least one idle field (VD intervals) before
the next exposure/readout can be triggered.

STROBE OFF Line/Pixel Position.
The same limitation applies to the triggering of the MSHUT
signal. There must be at least one idle field after the completion
of the MSHUT OFF operation before another MSHUT OFF
operation may be programmed.
The VSUB trigger requires two idle fields between exposure/
readout operations in order to ensure proper VSUB on/off trig-
gering. If the VSUB signal is not required to be turned on and
off in between each successive exposure/readout operation, this
limitation can be ignored. The VSUB Keep-On mode is useful
when successive exposure/readout operations are required.
