AD9898
MSHUT CONTROL
MSHUT Basic Operation
The AD9898 provides an MSHUT output pulse that can be
configured to control the mechanical shutter of the camera.
The registers used to control the MSHUT pulse are listed in
Table XXV.
The MSHUT pulse can be placed at the start of any line by using
the 11-bit MSHUTPOS register. The MSHUT pulsewidth is
controlled using the MSHUTLEN register.

The AD9898 offers four preprogrammed MSHUT patterns that
are selectable using the MSHUTPAT register. The
preprogrammed length is the same for all patterns set by the
MSHUTLEN register, but the active ON period of the
MSHUT pulse is different for each pattern, as shown in Figure
44. Figure 45 shows an example of selecting MSHUTPAT0
positioned to start three lines after the falling edge of VD with
MSHUTLEN = 5.
