Shutter Outputs
The AD9923A contains three shutter output pins: VSUB,
MSHUT, and STROBE. Internally, there are six possible shutter
signals available: VSUB0, VSUB1, SHUT0, SHUT1, SHUT2,
and SHUT3. Any of these signals, and the following combinations:
SHUT0 ^ VSUB0, SHUT0 ^ VSUB1, SHUT0 ^ SHUT1,
SHUT0 ^ SHUT2, can be mapped to any of the output pins
using the VSUB_CTRL, MSHUT_CTRL, and STROBE_CTRL
registers.

The VSUB signals behave differently than the SHUT signals,
and are generally used for the VSUB output pin. If a more generic
approach is desired for the shutter signals, the SHUT signals can
be used for the VSUB output pin.
It is also possible to configure the SYNC pin as an output and
send one of the internal shutter signals, or the combinations listed
above, to the SYNC pin using the TESTO_CTRL register
function. This provides the flexibility of outputting up to four
shutter outputs if the external SYNC input function is not needed.
VSUB Signal Operation
The CCD readout bias (VSUB) can be programmed to accom-
modate different CCDs. Figure 67 shows two available modes.
In Mode 0, VSUB goes active when the exposure begins during
the field of the last SUBCK. The on position (rising edge in
Figure 67) is programmable to any line within the field. VSUB
remains active until the end of the image readout. In Mode 1,
the VSUB is not activated until the start of the readout.
A function called VSUB_KEEPON is also available. When the
appropriate VSUB_KEEPON bit is set high, the VSUB output
remains active, even after the readout has finished. To disable
the VSUB at a later time, return this bit to low.
The AD9923A contains two programmable VSUB signals,
VSUB0 and VSUB1. Either of these signals can be mapped to
the VSUB output pin, the MSHUT pin, or the STROBE pin.
