The default shutter time was chosen to give a frame rate of 2.75 fps (see section 3.11
Controlling Frame Rate). Changing the shutter time involves writing to the three shutter
time registers.

3.10 Controlling Integration (Shutter Time)

The 6M3P allows you to control integration (also known as exposure time or shutter time)
in five ways.

The register settings required for each mode are defined in the following table
Table 14: Integration/Trigger Modes

* Indicates bit state not considered
Whenever the Integrate Mode or External Trigger Mode bits are set the MODE LED on
the right side of the rear cover will light to indicate that an externally synchronized mode
is active.

Programmed Integration/Free Running: (default) The camera free runs with the
internally programmed integration time and frame rate
Programmed Integration/SMA Trigger: The camera will integrate for the internally
programmed time when triggered by a TTL high pulse on the SMA connector.
Programmed Integration/Serial trigger: The camera will integrate for the internally
programmed time when triggered by high signal on the serial interface.
External Integration/SMA Trigger: The camera will integrate as long as the TTL
pulse on the TRIGGER IN SMA connector is high. The integration time is effectively
the input pulse width. In this mode, TRIGGER IN also controls the frame rate.
External Integration/Serial Trigger: The camera will integrate as long as the serial bit
is held high. The integration time is effectively the input pulse width. In this mode,
the serial signal also controls the frame rate. Due to variation in the host operating
system, this mode is generally used only for camera setup and functional testing.
