8.3 Status Registers
8.3.1 GrAVGH(80) & GrAVGL(81)
Bit #
Name
DIR
15:0 GrAVG
R
Default
Function
Green-Red pixel value average
The GrAVG registers make up a sixteen-bit register split across two 8-bit registers. The value is the average intensity value in a
12.4 fixed point format for all green pixels on the red row in the area defined by the ROI registers. The upper twelve bits are the
integer portion and the lower four bits provide a fractional value. This register is updated at the end of the active pixels and before
vertical blanking. The register always contains a valid value of the most recent frame.
8.3.2 GbAVGH(82) & GbAVGL(83)
Bit #
Name
DIR
15:0 GbAVG
R
Default
Function
Green-Blue pixel value average
The GbAVG registers are the average intensity value for all green pixels on the blue row in the area defined by the ROI registers.
This register is updated at the end of the active pixels and before vertical blanking. The register always contains a valid value of
the most recent frame.
8.3.3 RAVGH(84) & RAVGL(85)
Bit #
Name
DIR
15:0 RAVG
R
Default
Red pixel value average
Function
The RAVG registers are the average intensity value for all red pixels in the area defined by the ROI registers. This register is
updated at the end of the active pixels and before vertical blanking. The register always contains a valid value of the most recent
frame.
8.3.4 BAVGH(86) & BAVGL(87)
Bit #
Name
DIR
Default
Function
15:0 BAVG
R
Blue pixel value average
The BAVG registers are the average intensity value for all blue pixels in the area defined by the ROI registers. This register is
updated at the end of the active pixels and before vertical blanking. The register always contains a valid value of the most recent
frame.
8.3.5 LUMAVGH(88) & LUMAVGL(89)
Bit #
Name
15:0 LUMAVG
DIR
Default
R
Pixel value average
Function
The LUMAVG registers are the average intensity value for all pixels in the area defined by the ROI registers. This register is
updated at the end of the active pixels and before vertical blanking. The register always contains a valid value of the most recent
frame.
8.3.6 REPLPIX(A0)
Bit #
Name
7:0 REPLPIX
DIR
Default
Function
R
Number of Pixels Replaced
The REPLPIX register is a count of the number of pixels that have been replaced by the Pixel Replacement algorithm. If more
than 255 pixels have been replaced, the value is clipped to 255.
8.3.7 CURROW(A1)
Bit #
Name
7:0 CURROW
DIR
Default
Function
R
Eight MSBs of the Current row
The CURROW register contains the eight most-significant bits of the 11-bit Row counter. Thus, CURROW indicates where the
imager is currently reading data from the image array. Note that this value may jump quickly from one part of the image to the
