Draft
•In ExSync programmable mode, the rising edge of ExSync triggers exposure and charge
accumulation for a pre-programmed period of time. The lines are read out and transferred at
the end of the pre-programmed period. The falling edge of ExSync is irrelevant (see Figure 3-
5).
A parameter called “Exposure Time” is used to set the length of the pre-programmed exposure
period.

3.3.1.2 Selecting an ExSync Exposure Mode & Setting the Exposure Time
You can select an ExSync exposure time control mode and set the exposure time for the ExSync
programmable mode with the Camera Configuration Tool Plus (CCT+) or by using binary write
commands from within your own application to set the camera’s control and status registers
(CSRs).
With the CCT+
With the CCT+ (see Section 4.1), you use the Exposure Time Control Mode parameter in the
Exposure parameters group to select the ExSync edge-controlled, ExSync level-controlled or
ExSync programmable exposure time control mode. If you select the ExSync programmable
mode, you can use the Exposure Time parameter to set the exposure time.
By Setting CSRs
You select the exposure time control mode by writing a value to the Mode field of the Exposure
Time Control Mode CSR (see page 4-14).
If you select the ExSync programmable mode, you will also need to set the exposure time. You
set the exposure time by writing a value to the Absolute Exposure Time field or to the Raw
Exposure Time field of the Exposure Time CSR (see page 4-15).
Section 4.2.2 explains CSRs and the difference between using the “absolute” field and the “raw”
field in a CSR. Section 4.3.1 explains using read/write commands.
