8.3.18. User Data Area
The user data area is a FLASH data area reserved for the user, and the user can use the area to save
algorithm factors, parameter configurations, etc.
The user data area is 16K bytes and is divided into 4 data segments, each of which is 4K bytes. The user
can access the user data area through the API interface. The data is saved to the camera flash area
immediately after being written, and the data will not disappear after the camera is powered off.
8.3.19. Timer
The camera only supports one timer (Timer1), which can be started by a specified event or signal (only
ExposureStart signal is supported). The Timer can configure a timer output signal that goes high on a
specific event or signal and goes low after a specific duration. And the timer is cleared when the output
signal goes low. A schematic diagram of the timer working process is as follows:

The timer configuration process is as follows:
1. Set TimerSelector, currently only Timer1 supported.
2. Set LineSelector.
3. Set the LineSource to Timer1Active.
4. Set TimerTriggerSource, currently only ExposureStart supported.
5.

.
6.
