The ADE3XXX family of devices is capable of implementing all of the advanced features of today’s
LCD monitor products. For maximum flexibility, an external microcontroller (MCU) is used for
controlling the ADE3XXX and other monitor functions.
The ADE3XXX architecture unburdens the MCU from all data-intensive pixel manipulations,
providing an optimal blend of feature and code customization without incurring the cost of a 16-bit
processor or memory. The key interactions between the monitor MCU and the ADE3XXX can be
broken down into the features shown in the table below.
Table 1: ADE3xxx Features (Sheet 1 of 2)
Feature
Description of ADE3XXX Operation
Power Up / Initialize When power is first applied, the ADE3XXX is asynchronously reset from a pin.
The MCU typically programs the ADE3XXX with a number of default values and
sets up the ADE3XXX to identify activity on any of the input pins. All
preconfigured values and RAMs, such as DVI settings, line-lock PLL settings,
video input modes (YUV), OSD characters, LCD timing values (output
sequencer), scale kernels, gamma curves, sRGB color warp, APC dithering,
output pin configuration (OMUX), etc. can be preloaded into the ADE3XXX. The
typical end state is that the ADE3XXX is initialized into a low power mode, ready
to turn active once the power button is pressed.

Sync / Timing
Measurement
Once an input source is selected, all available information on frequencies and
SMEAS
line/pixel counts is measured for the selected source and made available to the
MCU.
32
Mode Set
Once the MCU has determined the matching video mode or calculated a video GLBL
mode using a GTF algorithm, the datapath is programmed to drive the flat panel. LLK
Clock frequencies for the internal memory and datapath are also set at this time. SRT

Autotune
When the MCU calls for an autotune, the MCU sets up an iterative loop to
search for the best phase, gain, offset, etc. At each step of the loop, the MCU
kicks off a test in which the ADE3XXX which performs extensive statistical
analysis of the incoming data stream. The results of the analysis are made
available to the MCU which is responsible for the optimization algorithm.
Digital Contrast /
Brightness
In response to user OSD control, the MCU can program single 8b registers that SRGB
set brightness and contrast for each color channel independently.

White Point Control In response to user OSD control, the MCU can program three 8b registers that
set the white point for the output.

Gamma
Adjustment
The MCU can program the gamma RAMs to implement 10b accurate color
transformations.

74
SRGB Control
The SRGB block allows simple, intuitive color control with just a few registers.
SRGB
64
Pattern Generation
For production testing, the ADE3XXX can be programmed by the MCU to output PGEN
a wide set of test patterns.
60
Flicker Reduction
For smart panel applications, the MCU can set up the flicker detection block to
report any correlation with the polarity inversion signal. The MCU can then
change the polarity inversion to a non-correlating pattern to eliminate flicker.
72
55
HDCP
The ADE3XXX contains the BlockCipher and Decryption functions - interactions HDCP
over DDC are managed by the MCU for maximum flexibility. The MCU models
the slow (frame rate, e.g. 60 Hz) authentication handshaking and state machine
whereas the ADE3XXX handles the fast (line rate, e.g. 50 kHz) decryption state
machine.
27
Backlight Control
The ADE3XXX provides two PWM outputs for direct control of the power
components in a typical backlight. The MCU sets up the registers and enables
the function.
PWM
77
Low Power State
To enter a low power state, the MCU can gate of most of the clocks and put the GLBL
analog blocks into a low power standby state. The DVI block will still report
activity in standby, allowing "wake on connection" operation.

Global Control Block
The global control block is responsible for:
●
Selecting Clock Sources
●
Power Control
●
I²C Control
●
SCLK Frequency Synthesizer Control
●
Block-by-Block Synchronous Reset Generation
The global control block runs on the XCLK clock domain which is required to be active for
programming. The clock domains of all other blocks are set in the Global Control Block. For I²C
access, the requested block must be driven with a valid clock above 10 MHz. Clock domains are
shown in Figure 2.

To program the SCLK frequency synthesizer to a desired frequency (fout, in MHz), the following
equations apply:

5
fOUT < fXCLK/8 AND fOUT ≥ fXCLK /16
6
fOUT < fXCLK/16 AND fOUT ≥ fXCLK /32
7
MD = INT(fXCLK x (2(6 + NDIV - SDIV)) / fOUT)
PE = INT((215) x (MD + 1 - fXCLK x (2(6 + NDIV - SDIV)) / fOUT))
where fXCLK is the external crystal frequency in MHz (typically 27). The maximum SCLK frequency
generated by this block is fXTAL x 2(2+NDIV).
For lower power operation, set all clock sources to the “zero” setting and also set the analog power
disables. In this condition, only the crystal clock domain (XCLK) runs and blocks in INCLK or
DOTCLK domains are not accessible by I2C.
To detect a DVI plug event and wake from a low power state, program the DVI detection clock
source select to the DVI detect clock and enable the analog power control for the DVI detect clock.
All other clock sources are set to zero.

FM Frequency Synthesizer
The FM frequency synthesizer creates a clock equivalent to up to eight times the crystal input clock,
using a digital frequency synthesizer. The modulation period and amplitude are directly controlled
by I2C registers. The I2C interface runs in the LLK_CTRL clock domain, which must be active for
access.
The output frequency (fOUT) is related to the 32-bit PHASE_RATE and crystal frequency (fXCLK) as
follows:
fOUT = fXCLK x 227+NDIV / PHASE_RATE
17/88
ADC Block
ADE3XXX
where fOUT and fXCLK are in MHz.
The maximum output frequency of the fm frequency synthesizer is fXTAL x 2(2+NDIV).
Note that native duty cycle of the fm frequency synthesizer is not 50/50. We recommend to either
enable the divide-by-two in the fm synthesizer block for frequencies up to fXCLK x 2(1+NDIV) (typically
108 MHz) or set the output mux to a double wide output mode for pixel clocks above fXCLK x
2(1+NDIV). This will ensure a 50% duty clock on the output.

ADC Block
The analog port consists of three 9-bit RGB ADCs with preamp, gain/offset adjustment and digital
filtering. The I2C interface for the ADC block is in the INCLK clock domain which must be active for
programming.
Input voltage, gain and offset register settings are approximately related to the output code. In this
equation, the output code (OUTPUT_CODE_8B) is equal to:
457 x offset / 28 + 181 x gain x input_mV / 216 - 125 x gain x offset / 216 - 219

Line Lock PLL Block
Line Lock PLL Block
The line lock PLL recovers a sample clock from an incoming hsync source. The response
characteristics of the line lock PLL are adjustable for optimimum response time and jitter filtering.
The phase of the sample clock is digitally adjustable by steps of 289 ps (with a 27-MHz crystal). The
I2C interface of the line lock PLL is in the LLK_CTRL clock domain which must be active for
programming.
The PLL loop filter has three ranges with independent filter parameters. When the phase detector
error remains below a programmable threshold for a programmable number of input lines, the loop
filter coefficients change. Any phase detector error above the programmed threshold reverts the
filter to the appropriate level in one line. The operation is represented in Figure 3.

error <= LOCK_TOL for
more than LOCK_LINE_NB
of lines
error <= SLOW_TOL for
more than SLOW_LINE_NB

lock

error > SLOW_TOL
error > LOCK_TOL
The digital loop filter is controlled by three parameters: MFACTOR, A and B. M_FACTOR is the
desired number of clocks per input line. The A and B parameters control the response of the 2nd
order digital filter. A and B are composed of a linear and exponential component designated by the
L and E suffix, respectively. These numbers are related to the classic 2nd order damping and
natural frequency as follows:
Damping = AL x 2(AE-12) x SQRT(5 x M_FACTOR / (BL x 2BE))
Natural Frequency = SQRT(M_FACTOR x 5 x BL x 2(BE-34))

Sync Retiming Block
The Sync Retiming (SRT) block retimes incoming synchronization signals (H Sync, V Sync, etc) into
the XCLK and INCLK domains.
For the XCLK domain, SRT has the following functionality:
●
Retimes all sync signals going to SMEAS into the XCLK domain.
●
Extracts vertical sync from composite sync signals (ahsync and acsync pins)
●
Divides clocks by 1024 for activity detection purposes.
●
Generates a delay-filtered version of vertical sync from a mux-selectable vertical sync source.
●
Generates a coast signal in the XCLK domain for the LLPLL.

ADE3XXX
Sync Measurement Block
The Input Sync Measurement Block (SMEAS) continuously detects activity from all video sources.
The module can measure the characteristics of the sync signals on any input port. The sync
measurement module reports the results of the measurements to the system microcontroller.
This portion of the sync measurement is fully synchronous on the crystal clock (XCLK). Another
block, the Sync Retiming Block (SRT), handles the asynchronous signal transfer of the incoming
sync signals.
Input Sync Functions:
●
Activity detection
●
Sync management
●

Data Measurement Block
The Data Measurement module measures several characteristics of the data and sync signals.
Data measurements are taken over a programmable window as defined by an upper left (mix_x,
min_y) and a lower right (max_x, max_y), which may be the whole frame. Measurements are
programmable either per color channel or over all color channels.
This module computes all measurements of sync and data format that are done in the INCLK
domain. The Sync Measurement module does measurements in the XCLK domain. The INCLKs
per DE measurement does not use the window feature. It measures the number of INCLK per DE
and returns the result for every line.
All unused or reserved bits return as zero.
Windows are relative to Sync pulses. A window defined from (0,0) - (0xFFF, 0xFFF) goes from sync
to sync. The reference edge to use, rising or falling, is also programmable per X and Y coordinates.
Configure SMUX to provide a positive polarity sync to the DMEAS block. All window enables reset
at 0 and always reset on the rising or falling edge of sync.
See the description of the specific PHM and DMM measurements performed within DMEAS here
below. Most algorithms are run over separate or all color channels. Most algorithms also contain a
threshold value to zero out noise and / or amplify edges. Algorithm, Color, Threshold, or Window
Control changes are accepted at the end of a valid measurement, the current measurement in
progress is not affected.
Software requests measurements in one of two ways:
42/88
●
One shot - synchronous with respect to the microcontroller.
●
Free Run - asynchronous with respect to the microcontroller.
ADE3XXX
Data Measurement Block
In One-shot mode, the block indicates that measurement is valid through an auto-clear of start
condition.
In Free-running mode, the block indicates that measurement is valid through a polling bit. In Freerunning mode, a freeze bit is provided to freeze the results. Measurements continue with the polling
bit active, but they are not updated if the Freeze bit is set.
2.12.1 Edge Intensity
The Edge Intensity measurement is the sum of the absolute value of the delta between adjacent
pixels. A programmable threshold is applied to zero out noise and amplify edges.
Equation:
Delta_val = abs(pixelA - pixelB) - threshold;
Delta_val = Delta_val < 0 ? 0: Delta_val;
Sum += Delta_val;
For all 3 color channels:
Sum += Delta_val on Red channel + Delta_val on Green channel + Delta_val on Blue channel
2.12.2 Pixel Sum
The Pixel Sum is the sum of all selected pixels for either a specific color channel or all color
channels within the window specified.
2.12.3 Min / Max
The Min / Max reports the minimum and maximum pixel found withing the window specified.
2.12.4 PCD
Pixel cumulative distribution function reports the total number of pixels greater than (or less than) a
programmable threshold.
To switch between pixels greater than or pixel less than the threshold, a control bit is provided in the
DMM_Mode register when requesting a measurement.
2.12.5 H Position Min / Max
Horizontal position measures the start and end of video data in INCLKs relative to the posedge of
hsync.
Data horizontal start is defined as the number of INCLKs between posedge of hsync and the "first
data pixel".
First data pixel is either:
●
first pixel greater than the programmable threshold value, or
●
first pixel with the absolute value (current pixel - previous pixel) is greater than the
programmable threshold value
Data horizontal end is defined as the number of INCLKs between posedge of hsync and the "last
data pixel plus one". The search for the last pixels ends at the end of a window.
Last data pixel plus one is either:
●
pixel after the last pixel that is greater than the programmable threshold value,or
●
last pixel with the absolute value(current pixel - previous pixel) is greater than the
programmable threshold value.
When measurement is required, a control bit in the DMM_Mode register is used to switch between
the two threshold methods for first and last pixels.
43/88
Data Measurement Block
ADE3XXX
The first and last pixels are measured for each line, and the earliest first and latest last for the
selected pixel area are reported out at the end of the measurement. The intention is that "last data
pixel plus one" minus "first data pixel" is equal to the horizontal width of the video format.
2.12.6 V Position Min / Max
Vertical position measures the start and end of video data in hsyncs relative to the posedge of
vsync.
Data vertical start is defined as the number of hsyncs between posedge of vsync and the "first data
pixel line".
First data pixel line definition is the first line with at least one pixel greater then the programmable
threshold.
Data vertical end is defined as the number of hsyncs between posedge of vsync and the "first
blanking line after data plus one". The first blanking line is detected and confirms that each
subsequent line contains no data pixels. The confirmation of the first blanking line measurement
ends at the posedge of vsync.
First blanking line after data definition is the row after the last row with at least one pixel greater than
the programmable threshold.
The first and last data pixel lines are measured within a frame. The earliest first and latest last data
pixels corresponding to the selected pixel area are reported out at the end of the measurement. The
intention is that "data vertical end plus one" minus "data vertical start" is equal to the vertical height
of the video format.
2.12.7 DE Size
DE Size measures the number of INCLKs per data enable. DVI input measures precisely the input
image horizontal size.
At the end of the measurement (DE falling edge), the measured value is compared to a
programmed expected value +/- a programmed threshold. If the expected value is within the
threshold, the DE_size_mismatch flag is not set. If the measued size is outside the threshold, the
DE_size_mismatch flag is set.
In Free-running mode, results are updated at every line. The DE_size_mismatch flag is set at DE
falling edge and reset at DE rising edge.
In One-shot mode, results are updated once and kept until they are cleared by software. The
DE_size_mismatch flag can only be cleared when the reset flag bit is set by software.

Programmable Nonlinearity Block
The programmable nonlinearity (PNL) block performs a gamma type enhancement to all color
channels prior to the scaler to suppress halo and roping effects. For best performance, tune the
48/88
ADE3XXX
Scaler Block
PNL block to the LCD gamma value, then the post-scaler gamma RAM implements the
corresponding inverse gamma function.

Scaler Block
The scale module resizes images from one resolution to another. For this, a 3x3 non-separable
scaling filter performs a dot product of the input pixel values with a weighting vector computed from
the chosen filtering function. To sharpen text without introducing excessive artifacts, the output pixel
contrast level is adjusted with the context value measured over a 3x3 grid in the relevant area of the
source image.
For proper scaler operation, set the SCLK frequency to be greater than the max of dclk and
in_hpixel x dclk_freq / (dest_hpixel x pixel_avg).

Output Sequencer Block
The output sequencer module provides timing for the output video interface. It allows sufficient
flexibility to support a broad range of Smart Panel applications as well. The timing unit is based on
horizontal and vertical counters, which are locked with the input video stream.
Figure 4: Output Sequencer Block Diagram
Frame Synchronization
Due to the limited pixel memory of the chip, the output active video needs to be perfectly
synchronized with the input active video. This mode of operation is called Frame Lock.
Figure 5: Frame Lock Operation
Timing Unit
The timing unit consists of a 12-bit horizontal and a 12-bit vertical counter, synchronized with the
input video stream.
Signal Generation
The signal generation unit generates all fixed control signals like hsync, vsync and data enable as
well as those required to run the internal data path. Also included, a generalized timing section
supports flat panel TCON signals like polarity and other control signals.

Pattern Generator Block
The integrated Pattern Generator displays a set of graphic patterns to help debugging systems and
test LCD panels. It is located ahead of the color management block, all generated colors are subject
to further transforms.
The screen can be split into a programmable grid of up to 8x8 areas. One of two independent
programmable patterns are displayed in each area.
Screen Split
A set of eight Grid registers grid0 - grid7, each with 8 bits, represents a block map of the grid (8x8
blocks). Each bit from the Grid registers represents one rectangular (gridX)x(gridY) block of pixels
which covers the LCD screen display area. Within these registers, a 0 selects Pattern 0 (defined
below) and a 1 selects Pattern 1.
Figure 7: Pattern Generator: Screen Split
All cells are the same size, defined by one horizontal and one vertical grid block size registers gridX
and gridY.

Pattern Generator Block
When the programmed block size corresponds to a larger 8x8 grid than the total screen area, only
the blocks or part of blocks included in the output screen space are rendered. The 8x8 block set is
upper left justified. All blocks from the right and bottom sides which are outside the total display area
are not rendered.
When the programmed block size corresponds to a smaller 8x8 grid than the total screen area, the
part of the screen area which is outside the 8x8 grid is forced to black.
Pattern Engine
The pattern generator has two pattern display engines to display two patterns simultaneously on the
LCD screen. Each engine displays horizontal or vertical bicolor stripes, bicolor checkers, color bars,
gray scales or color scales. It is also possible to select the video stream from the scaler as a pattern.
The pattern engine displays a bi-directional x-y symmetric pattern. Two 24b colors, C0 and C1, are
alternately displayed with a horizontal period of Width and vertical period of Height. Programming a
large Width and a small Height generates horizontal bars whereas the opposite generates vertical
bars. Programming small numbers for Width and Height generates checker patterns.
Both patterns are also given X and Y offset attributes, they can be centered inside the grid blocks.
A gradient effect can be applied independently on each pattern, to either or both horizontal and
vertical directions. The gradient effect takes two parameters: STEP and DELTA that define a ramp.
Borders
The border generator adds a single pixel width border to the whole display area. Each side color of
the display is selectable among 8 independent colors.

SRGB Block
The sRGB block performs two primary functions:
1. Parametric gamma correction on multiple windows or full screen for video enhancement in a
window and digital contrast/brightness control. The window coordinates are set by TCON
registers.
2. 3D color cube warping RGB color space.
2.18.1 Parametric Gamma Correction and Digital Contrast/Brightness Control
The function is applied to the entire window by programming the window control to full screen.
Each color channel acts independently. Simple digital contrast and brightness are programmable
with this hardware function. The desired window coordinates are programmed into the TCON.
2.18.2 Color Space Warp
The 8 corners of the color cube are independently controlled in 3D space with smooth interpolation
of intermediate colors. Registers are 2’s complement color delta’s. For example, to make WHITE
more like RED, program SRGB_WHITE_R to a small positive value.

OSD Access via I2C
The OSD uses a dedicated memory space accessible through an I2C port. The data stream sent to
the OSD register starts with two header bytes. These specify the type of transfer and the row/
column position for screen map transfers, the character index for font definition transfers, or the
color index for color map transfers.
A stream of OSD writes to the OSD I2C register can fill in a segment of the OSD memory space with
an internal auto-incrementing index register. The protocol is as follows:
1. Issue a start sequence with the R/W bit set to W.
2. Write to the OSD register. The first byte transferred is the index of the first internal OSD
register to be written. The next byte contains the data to be written to that register. Subsequent
bytes are written to successive internal OSD registers.
3. Continue writing data bytes until the desired range of OSD internal registers has been written
(the ADE3XXX device will issue an ACK on each transfer).
4. Issue an I2C stop sequence.
Character Display
There are two 96-character monochrome fonts and two 32-character four-bit color fonts, a total of
256 characters. The four bits of color are an index into one of two 16 entry color look-up tables.
Entries in the color look-up table specify a 24-bit RGB color. All fonts and the color look-up table are
RAM-based and must be downloaded to the OSD’s internal RAM before use. Font addressing is as
follows: character indexes 0x00-0x1F refer to color font 0, 0x20-0x7F refer to monochrome font 0,
0x80-0x9F refer to color font 1 and 0xA0-0xFF refer to monochrome font 1.
Screen Map
The OSD uses a character map of 15 rows x 30 columns. Each character occupies one byte. The
value of each byte indicates the character to display.
The OSD character map is addressed by specifying the row and column as part of the data transfer.
Attribute Map
The attribute map is defined as 16 rows by 31 columns. It has an extra row and an extra column
compared to the screen map.
The values corresponding to printable row/column addresses provide character attributes. Each
character on the screen has an attribute byte specifying (in the case of monochrome fonts) three
bits of background color, four bits of foreground color, and a blink on/off bit.
Blinking, when enabled, has a period of 100 frames (50 frames on, 50 frames off).
Column 31 of each row contains row attributes. These include the fourth bit of the background color
and two bits controlling double-height and double-width text.
Row 15 contains global attributes, including vertical and horizontal OSD position on the screen,
alpha blending, shadow/bordering, OSD rotation, color map selection, and normal/double size.
Alpha blending allows the OSD display to be mixed with the incoming video signal for transparency
67/88

ADE3XXX
effects. An alpha value of 255 makes the OSD opaque, while a value of 0 makes the OSD invisible,
with a linear ramp of transparency between these two endpoints. Separate registers control alpha
for foreground and background pixels.
A fade-in/fade-out feature ramps the alpha values every six frames, starting from their current value
and going up or down the sequence: 0, 16, 32, 64, 128, 192, 224, 240, 255.
Row 15 also contains definitions for the four display windows. These windows define regions on the
screen to which borders and shadows can be applied. (They are not analogous to windows in a GUI
display, in that they do not represent four independent data displays. There is only one character
map. The windows essentially define an area around which a border can be drawn or to which
attributes can be assigned.) Windows also determine which of the two color tables will be used for
the characters inside. Windows have a fixed precedence: window 0 has the highest precedence
and window 3 the lowest. When windows overlap, the precedence determines which borders will be
displayed and which color tables will be used in the overlapping area.

Monochrome and color fonts are affected differently by attribute bytes. Monochrome characters are
affected by shadows and borders, and have their color specified by the foreground/background
attributes. Color characters interpret the attribute byte differently than monochrome characters,
using it to define blinking and 90-degree rotations rather than blinking, foreground color, and
background color.
Color Tables
There are two color tables, each containing sixteen entries by three bytes each, giving a 24-bit RGB
value for each entry. Entry 0 is used for the shadow color for monochrome characters and borders.
Color-table selection is made on a window-by-window basis.
When writing the color table, the “row” value in the first header byte is interpreted as the color table
index, while the “column” value in the second header byte encoded to select the color table (0 or 1)
68/88
ADE3XXX
OSD Block
and the primary color (red, green, or blue). The data byte following the second header byte is
written to the selected (table, index, primary) location.
Font Data
Font data is sent to the OSD through burst transfers. The first header byte selects the transfer type
and provides three bits of the character index, while the second header byte selects transfer type
“C” and gives the remaining five bits of offset. The data bytes for the character follow, given from top
to bottom and left to right in the character cell.
A monochrome character is 27 bytes long, with two scan-lines occupying three bytes. A color
character is four times as long as a monochrome character (108 bytes), with each byte containing
two four-bit pixels. Both color and monochrome fonts are 12 pixels wide and 18 high.
Transfer Formats
The transfer format consists of two header bytes and a variable number of data bytes. The header
bytes determine the type of transfer (character, attribute, monochrome font, color font, or color
table). Addressing is by row and column in the case of character or attribute transfers, and by
character index in the case of font transfers.
When writing to the color table, the “column” field determines the color table and R/G/B selection.

[7:4]
Type of data transfer. Valid values are:
0x8: screen map
0x9: color LUT
0xA: attribute map
0xC: font data
all others: Reserved

For screen map or attribute map access, this is the row index.
For color LUT access, this is the color index.
For font data access, bits [2:0] are the MSB’s of the character index.

Type of data burst:
0x0: A/B modes: Only one data byte follows this header byte.
0x1: C mode: All bytes following this header byte are data bytes until
the serial interface indicates an end-of-transmission. The OSD
internally auto-increments after each byte. In screen and attribute map
access modes the column number is incremented after each byte,
wrapping to the beginning of the next row once column 29 is passed
and wrapping to row 0 if row 14 is passed.
Either mode may be used for display and character attribute modes,
except for the off-screen attributes in column 15 and row 30, which
must use mode A/B. Font definition mode must use mode C.
[5]
must be set to zero
[4:0]
In screen and attribute map access modes, this is the column number.
In font data access mode, this gives the 5 lsb’s of the character index.
In color LUT access mode, it selects the table number and color to be
written:
0x0: LUT 0, red
0x1: LUT 0, green
0x2: LUT 0, blue

Flicker Block
The Flicker block computes correlations of the image data with potential inversion patterns of the
LCD which in turn allows the microcontroller to modify the polarity signal to cancel large area flicker.
This function is only useful in SmartPanel applications.
The incoming image is scored against 8 vertical Walsh functions. All patterns are considered to be
vertically, where horizontally the pixels are assumed to be alternating its RGB components.
The scores (0 to 7) are 32-bit unsigned quantities that reflect the correlation of the programmed
window area with the 8 Walsh functions.
The horizontal inversion of the LCD drivers must be programmed into FLICKER_CTRL0[2:0]. The
most common setting is +-+ or -+- (RGB).
A calculation is completed after the number of frames programmed into the FRAME_CNT_MAX reg
(0xCA03). With each frame, the calculation is performed on only a vertical strip. The width of that
strip (in pixels) is determined by the value programmed in the HBLOCK_SIZE reg (0xCA02) with the
following relation: strip width = 2 ^ (3 + HBLOCK_SIZE).
The FREE_RUN/FREEZE_SCORES bit (FLICKER_CTRL0[4]) enables the final calculation to be
captured easily by the microntroller. The internal flicker calculation continues to run -- only the
update of the I2C registers is blocked when this bit is set to prevent corrupution during readout.

Description
Number of Frames to complete one
measurement
total number of pixels in a line is:
FRAME_CNT_MAX x (2 ^ (3 +
HBLOCK_SIZE) )
example: HBLOCK_SIZE = 4;
FRAME_CNT_MAX = 8;
In each frame only one portion of the image
is being scored. The width of that portion is
2 ^ (3 + HBLOCK_SIZE) = 128 pixels and
the height is the full height of the image.
Thus the total scored area after 8 frames is
128 x 8 = 1024 pixels wide.

The RAMs are individually programmable (read and write) using I2C access. The memory map is
as follows:
I2C address 0x1000 - 0x11FF: red RAM
I2C address 0x1200 - 0x13FF: green RAM
I2C address 0x1400 - 0x15FF: blue RAM
Even addresses are the 8-bit LSBs of the 10-bit gamma value. Odd addresses are the 2 MSBs.

APC Block
APC (formerly known as Arithmos Perfect Color) dithers an input 10-bit video stream down to 4-8
output bits. The dithering is done in space and time in such a way that the eye does not perceive
objectionable artifacts such as:
74/88
●
fixed dither patterns,
●
contours,
●
flickering pixels
●
phase correlated flickering, which creates wave patterns known as "swimming".

Pulse Width Modulation (PWM) Block
The PWM B block generates two signals to control backlight inverter switching power components
directly. It is derived from XCLK and powered up independently of the DOTCLK and INCLK
domains. Frequency, duty cycle, polarity and overlap/non-overlap are programmable. The output
frequency can “free-run” or lock to output vsync.
