ROI_XOFF[15:8]
ROI_XON[7:0]
The ROI 1 register is used to specify the size and location of the region of interest box in the x axis (imager columns). The bits
are defined as follows:
[15:8] ROI_XOFF:
[7:0] ROI_XON :
This field specifies the 8 most significant bits of the ending X coordinate. The least significant bits are
fixed at “000”. Therefore, the resolution of this coordinate is limited to multiples of 8.
This field specifies the 8 most significant bits of the starting X coordinate. The least significant bits are
fixed at “000”. Therefore, the resolution of this coordinate is limited to multiples of 8.

ROI_YOFF[15:8]

The ROI 2 register is used to specify the size and location of the region of interest box in the x axis (imager rows). The bits are
defined as follows:
[15:8] ROI_YOFF:
[7:0] ROI_XON :
This field specifies the 8 most significant bits of the ending Y coordinate. The least significant bits are
fixed at “00”. Therefore, the resolution of this coordinate is limited to multiples of 4.
This field specifies the 8 most significant bits of the starting Y coordinate. The least significant bits are
fixed at “00”. Therefore, the resolution of this coordinate is limited to multiples of 4.

The Video control register is used to enable various features that affect the output video signal.
[15] Reserved:
[14] TINT_HYST:
This bit is reserved for future use and should not be set. To ensure compatibility with future
releases, we recommend using a read/modify/write operation to preserve the status of this bit.
Writing a ‘1’ to this bit will cause the automatic control of the Tint settings to have additional
hysteresis. This added hysteresis will cause changes of less than two lines to be suppressed.
This is useful in eliminating the appearance of flickering in very bright scenes where a change
of one line of integration time represents a significant change in image brightness.
