Example of Exposure and Readout of Interlaced Frame
Figure 35 shows the sequence of events for a typical exposure and
readout operation using a mechanical shutter and strobe. The
register values for the VSUB, MSHUT, and STROBE toggle
positions may be previously loaded at any time, prior to triggering
these functions. Additional register writes are required to configure
the vertical clock outputs, V1–V4, which are not described here.

Write to the TRIGGER Register (Addr x280) to enable the
STROBE, MSHUT, and VSUB signals. To trigger all three
signals (as in Figure 36) the register TRIGGER = 7.
