Pattern Generation
The sensor can be configured to send a fixed pattern. The pattern generation is configurable through
the SFNC
TestPattern
register.

Sensor normal operation, the image is coming
from the sensor
Black
Generate frames with fixed pixels values 0x00
(8 bits) or 0x000 (12 bits)
White
Generate frames with fixed pixels values 0xFF
(8 bits) or 0x3FF (12 bits)
GreyHorizontalRamp
Generate frames with pixels values from 0x00
to 0xFF in 8 bits and from 0x000 to 0x3FF in 12
bits mode

from left to right at each frame.
The test pattern is OFF by default.
The Black, White and GreyHorizontalRamp patterns are generated in the sensor. They can be useful
when developing a software to control the camera or to troubleshoot the CoaXPress links.
The SimulatorGreyHorizontalRamp and SimulatorGreyHorizontalRampMoving are generated in the
camera FPGA.
