Registers
Micron Confidential and Proprietary
Bits 9:0 Row Noise
Constant
Constant used in the row noise cancellation algorithm. It
should be set to the dark level targeted by the black level
algorithm plus the noise expected between the averaged
values of the dark columns. The default constant is set to
42 LSB.
2A N Y
R89—0x59 - Black Rows (R/W)
Bits 7:0 Black Rows For each bit set, the corresponding dark row (rows 0–7) are
used in the black level algorithm. For this to occur, the
reading of those rows must be enabled by the settings in
R0x22:0.
FF N N
R91—0x5B - Green1 Frame Average (R/O)
Bits 6:0 Green1 Frame
Average
The frame-averaged green1 black level that is used in the
black level calibration algorithm.
R92—0x5C - Blue Frame Average (R/O)
Bits 6:0 Blue Frame
Average
The frame-averaged blue black level that is used in the
black level calibration algorithm.
R93—0x5D - Red Frame Average (R/O)
Bits 6:0 Red Frame
Average
The frame-averaged red black level that is used in the black
level calibration algorithm.
R94—0x5E - Green2 Frame Average (R/O)
Bits 6:0 Green2 Frame
Average
The frame-averaged green2 black level that is used in the
black level calibration algorithm.
R95—0x5F - Threshold (R/W)
Bits 14:8 Upper
Threshold
Upper threshold for targeted black level in ADC LSBs.
23 N N
Bits 6:0 Lower
Threshold
Lower threshold for targeted black level in ADC LSBs.
1D N N
R96—0x60 - Calibration Control (R/W)
Bit 15 Disable Rapid
Sweep Mode
Disables the rapid sweep mode in the black level algorithm.
The averaging mode remains enabled.
0 Y N
Bit 12 Recalculate When set, the rapid sweep mode is triggered if enabled,
and the running frame average is reset to the current frame
average. This bit is write - 1, but always reads back as “0.”
0 Y N
Bit 10 Limit Rapid
Sweep
1—Dark rows 8–11 are not used for the black level
algorithm controlling the calibration value. Instead, these
rows are used to calculate dark averages that can be a
starting point for the digital frame-wise black level
algorithm.
0
—All dark rows can be used for the black level algorithm.
This means that the internal average might not correspond
to the calibration value used for the frame, so the dark row
average should in this case not be used as the starting point
for the frame-wise black level algorithm.
