Set the Chroma at pattern 63 (cross-talk pattern) or WIN 9 8 / 95 sh ut - down mode (dot-pattern). Adjust until the vertical-Stripe-shadow as wide as possible or no visible. This function is adjust the PLL divider of ADC to generate an accurate pixel clock Example : Hsyn = 31.5KHz Pixel freq. = 25.175MHz (from VESA spec)

The Divider number is (N) = (Pixel freq. x 1000)/Hsyn

From this formula, we get the Divider number, if we fill this number in ADC register (divider register), the PLL of ADC will generate a clock which have same period with above Pixel freq.(25.175MHz) the accuracy of this clock will effect the size of screen.(this clock was called PIXEL-CLOCK)

3. Focus adjustment

Set the Chroma at pattern 63 (cross talk pattern) or WIN98 / 95 sh ut do w n mode (dot-pattern). Adjust the horizontal interference as less as possible This function is adjust the phase shift of PIXEL-CLOCK to acquire the right pixel data . If the relationship of pixel data and pixel clock not so match, we will see the horizontal interference on screen ,we only find this phenomena in crosstalk pattern or dot pattern , other pattern the affect is very light

4. H/V-Position adjustment

Set the Chroma to pattern 1 (crosshatch pattern) or WIN98/95 full-white pattern confirm above item 2 & 3 functions (clock & focus) was done well, if that 2 functions failed, the H/V position will be failed too. Adjust the four edge until all four-edges are visible at the edge of screen.

5. MULTI-LANGUAGE function

There have 5 language for selection, press “MENU” to selected and confirm , press “ LEFT” or “ RIGHT” to change the kind of language ( English , Deutch , Francais, Espanol, Italian)

Press power key and check U302 pin 43 = low (0V) ?

Check U302 pin 38 (LED green) will have transition from hi to low or low to hi when we press the power key??

Check U302 pin 20= 20MHz ? and pin 44 (VDD)=5V ? and pin 10 (reset)=0V ? at normal condition

Without press key and change mode, Check U302 pin 16,17(sda,scl)= hi 5V ? or keep transition ?

Replace U302 MCU

NG, MCU no response

Keep transition, that means eeprom no response

Mechanical was stuck, Check !

Replace Tact-switch SW105 at keyboard if still no work replace U302 MCU at main-board and check MCU relative reset circuit, and crystal

If still no Led green indicator, check Q102, R106 & LED at keyboard !! cold solder or bad

If one of this item was NG, check the relative circuit

Check U300 eeprom 24LC04 relative circuit, check U300 pin 7 = low?

Check JP202 is connect ?

Check U300 pin 8 (vdd)= 5V, and check R300

R301 cold solde

Replace eeprom

POWER-BLOCK check **Note : the Waveform of U304 pin 2 can determined the power situation

1. stable rectangle waveform with equal duty, freq aroun d 150 K- 1 58 K Hz

that means all power of this interface board is in normal operation ,and all status of 5V & 3.3V is working well

2. unstable or uneven rectangle waveform without same duty, that means ABNORMAL operation was

happened, check 3.3V or 5V ,if short-circuit or ba d component

3. rectangle waveform with large spike & harmonic pulse on front side , means all 3.3v is no load, U200

Gmzan1 was shut-down, and only U302 MCU still working , that means the monitor is in power saving status , all power system is working well .

Measure input power at U304 LM2596 pin 1= 12V ?

Check ADAPTER and connector if loose?

Check U304 pin 2 is a stable rectangle wave? Around 150k-158kHz stable rectangle wave with equal duty without any spike or harmonic pulse?

The interface board power is good

Check U304 pin 2 is a unstable rectangle wave ?

OK, unstable wave

Check all 3.3V & 5V power, there is short circuit or bad component was happened

NG, with harmonic

ulse

The interface board is in powersaving state, press power key to wake up & check your signal input

III.ALL SCREEN HAS INTERFERENCES OR NOISE, CAN’T BE FIXED BY AUTO KEY

** NOTE: There is so many kind of interferences, 1). One is cause by some VGA-CARD that not meet VESA spec or

power grounding too bad that influence our circuit

2).other is cause by external interferences, move the monitor far from electronic equipment.( rarely happened)

Use DOT-pattern, or win98/99 shut-down mode pattern, press “AUTO” key, was the interferences disappear ??

Adjust “FOCUS” step by step, until the horizontal interferences disappear

Does your signal-cable have an additional cable for extension ??

Does your noise only exist in one mode only? (ex: only at 1280x1024 @ 75 Hz, other is normal)

That was cause by you VGA-CARD setting, your VGA card timing backporch/frontporch exceed vesa timing too far, for some new AGP-VGA-CARD such situation always happened So in your control-panel icon ,select monitor ,setting ,

advance ,screen-adjust,at Size icon, increase step by step slowly, press “”AUTO”

key every step you increase the SIZE . repeat the procedure( increase/decrease SIZE one-step and press AUTO) until the interferences disappear, press “APPLY” to save in your VGA

NO additional extension cable

Yes, only happened on one mode

Yes, has extension

END

Put away the additional cable May be the additional cable grounding is not quite well

Change the Signal-cable to new-one or Try other brand VGA-CARD (make sure just only that brand VGACARD has this problem ,contact RDtai

There is an interferences in DOS MODE

NOTE :the criteria of doing AUTO-CONFIGURATION : must be a full-size screen, if the screen not full , the autoconfiguration will fail. So in dos mode ,just set your “CLOCK” in OSD-MENU to zero or use some EDITOR software which can full fill the whole screen (ex: PE2, HE) and then press “AUTO” Or you can use “DOS1.EXE” which attached in your Driver disk to optimize DOS mode performance

V. THE PANEL LUMINANCE WAS DOWN

Use white pattern and resolution 1280x1024 @ 60Hz , CHROMA 7120 measured the center of panel

Set Contrast, brightness =maximal, RGB= 50 Quit from OSD-screen, measured Y(luminance) With chroma 7120, check Y= 240±10 CD/M2 ?

If Y can reach ＞190 cd/m2 that means The lamp still working well, so we just re-do the white-balance process As following procedure

Adjust VR201 until maximal, measured Y = 240±10 cd/m2 ?

Use white-pattern, press MENU button along with AC power-plug in ( you will in factory mode) The OSD-menu will be at left-top of screen,

If the Y less than 160 cd/m2 (after the VR201= MAX, contrast, brightness = max) then change the LAMP of panel

press AUTO button to automatically adjust blacklevel value, you will see the sign PASS ,if FAIL , manual adjust the blacklevel until value 43 !

Set contrast, brightness to max, and turn the VR201 to max , wait for 20 minutes until the luminance Y stable The Y should be larger than 200 cd/m2 (for panel which already use for a year, the Y luminance might be a little down, around 180 cd/m2, there is acceptable too)

Follow this manual page 7 item 4-2 method to more detail procedure for do a white-balance adjust

1.5 Operating Modes

The Source Clock (also called SCLK in this document) and the Panel Clock are defined as follows: z The Source Clock is the sample clock regenerated from the input Hsync timing (called clock recovery) by

SCLK DDS (direct digital synthesis) and the PLL.

z The Panel Clock is the timing clock for panel data at the single pixel per clock rate. The actual PCLK to the

panel may be one-half of this frequency for double-pixel panel data format. When its frequency is different from that of source clock, the panel clock is generated by Destination Clock (or DCLK) DDS/PLL.

There are six display modes: Native, Slow DCLK, Zoom, Downscaling, Destination Stand Alone, and Source Stand Alone. Each mode is unique in terms of:

z Input video resolution vs. panel resolution z Source Clock frequency / Panel Clock frequency ratio z Source Hsync frequency / Panel Hsync frequenc ratio z Data source (analog RGB, panel background color, on-chip pattern generator

1.5.1 Native

Panel Clock frequency = Source Clock frequency Panel Hsync frequency = Input Hsync frequency Panel Vsync frequency = Input Vsync frequency

This mode is used when the input resolution is the same as the panel resolution and the input data clock frequency is within the panel clock frequency specification of the panel being used.

1.5.2 Slow DCLK

Panel Clock frequency < Source Clock frequency Panel Hsync frequency = Input Hsync frequency Panel Vsync frequency = Input Vsync frequency

This mode is used when the input resolution is the same as the panel resolution, but the input data clock frequency is exceeds the panel clock frequency specification of the panel being used. The panel clock is scaled to the Source Clock, and the internal data buffers are used to spread out the timing of the input data by making use of the large CRT blanking time to extends the panel horizontal display time.

1.5.3 Zoom

Panel Clock frequency > Source Clock frequency Panel Hsync frequency > Input Hsync frequency Panel Vsync frequency = Input Vsync frequency

This mode is used when the input resolution is less than the panel resolution. The input data clock is then locked to the pnael clock, which is at a higher frequency. The input data is zoomed to the panel resolution.

1.5.4 Downscaling

Panel Clock frequency < Source Clock frequency Panel Hsync frequency < Input Hsync frequency Panel Vsync frequency = Input Vsync frequency

This mode is used when the input resolution is greater than the panel resolution, to provide enough of a display to enable the user to recover to a supported resolution. The input clock is operated at a frequency less than that of the input pixel rate(under-sampled horizontally) and the scaling filter is used to drop input lines. In this mode, zoom scaling must be disabled

1.5.5 Destination Stand Alone

Panel Clock = DCLK in open loop (not locked) Panel Hsync frequency = DCLK frequency / (Destination Htotal register value) Panel Vsync frequency = DCLK frequency / (Dest. Htotal regi st er val ue * Dest. Vt ot al regi st er value)

This mode is used when the input is chang ing or not available. The OSD may still be used as in all other display modes and stable panel timing signals are produced. This mode may be automatically set when the gmZAN1 detects input timing changes that could cause out- of-spec operation of the panel.

1.5.6 Source Stand Alone

Panel Clock = DCLK in open loop (not locked to input Hsync) Panel Hsync frequency = SCLK frequency / (Source Htotal register value) Panel Vsync frequency = SCLK frequency / (Source Htotal register value *Source Vtotal register value)

This mode is used to display the pattern generator data. This mode may be useful for testing an LCD panel on the manufacturing line (color temperature calibration, etc.).

2.2 Clock Recovery Circuit

The gmZAN1 has a built-in clock recovery circuit. This circuit consists of a digital clock synthesizer and an analog PLL. The clock recovery circuit generates the clock used to sample analog RGB data (SCLK or source clock). This circuit is lo cked to the HSUNC of th e inc oming video signal. Th e RCLK generated from the TCLK input is used as a reference clock.

The clock recovery circuit adjusts the SCLK period so that the feedback pulse generated every SCLK period multiplied by the Source Horizontal Total value (as programmed into the registers) locks to the rising edge of the Hsync input. Even though the initial SCLK frequency and the final SCLK frequency are as far apart as 60MHz , locking can be achieved in less than 1ms across the operation voltage/temperature range.

The SCLK frequency (1/SCLK period) can be set to the range of 10-to-135 MHz. Using the DDS (direct digital

synthesis) technology the clock recovery circuit can generate any SCLK clock frequency within this range.

The pixel clock (DCLK or destination clock) is used to drive a panel when the panel clock is different from SCLK (or SCLK/2). It is generated by a circuit virtually identical to the clock recovery circuit. The difference is that DCLK is locked to SCLK while SCLK is locked to the Hsync input. DCLK frequency divided by N is locked to SCLK frequency divided by M. The value M and N are calculated and programmed in the register by firmware. The value M should be close to the Source Htotal value.

The table below summarizes the characteristics of the clock recovery circuit.

SCLK Frequency 10MHz 135 MHz Sampling Phase Adjustment 0.5 ns/step, 64 steps

Patented digital clock synthesis technology makes the gmZAN1 clock circuits very immune to temperature/voltage drift.

2.2.1 Sampling Phase Adjustment

The ADC sampling phase is adjusted by delaying the Hsync input at the programmable delay cell inside the gmZAN1. The delay value can be adjusted in 64 steps, 0.5 ns/step. The accuracy of the sampling phase is checked by the gmZAN1 and the “score” can be read in a register. This feature will enable accurate auto-adjustment of the ADC sampling phase.

2.2.2 Source Timing Generator

The STG module defines a capture window and sends the input data to the data path block. The figure below shows how the window is defined. For the horizontal direction, it is defined in SCLKs (equivalent to a pixel count). For the vertical direction, it is defined in lines. All the parameters in the figure that begin with “Source” are programmed into the gmZAN1 registers. Note that the vertical total is solely determined by the input. The reference point is as follows:

z The first pixel of a line: the pixel whose SCLK rising edge sees the transition of the HSYNC polarity from low

to high.

z The first line of a frame: the line whose HSYNC rising edge sees the transition of the VSYNC polarity from low

to high.

The gmZAN1 also supports the use of analog composite sync and digital sync signals as described in Section 2.3.2

The gmZAN1 ADC has a built-in clamp circuit. By inserting series capacitors (about 10 nF) the DC offset of an external video source can be removed. The clamp pulse position and width are programmable.

2.3.2 Sync. Signal Support

The gmZAN1 chip supports digital separate sync (Hsync/Vsync), digital composite sync, and analog composite sync (also known as sync-on-green). All sync types are supported without external sync separation / extraction circuits.

Digital Composite Sync

The types of digital composite sync inputs supported are:

z OR/AND type: No Csync pulses toggling during the vertical sync period z XOR type: Csync polarity changes during the vertical sync period

The gmZan1 provides enough sync status information for the firmware to detect the digital composite sync type.

Sync-On-Green (Analog Composite Sync)

The voltage level of the sync tip during the vertical sync period can be either –0.3V or 0V

2.3.3 Display Mode Support

A mode calculation utility (MODECALC.EXE) provided by Genesis Microchip may be run before compilation of the firmware to determine which input modes can be supported. Refer to firmware documents for more details.

2.4 Input Timing Measurement

As described in section 2.2.2 above, input data is sent from the analog-to-digital converter to the source timing generator (STG) block. The STG block defines a capture window (Figure5).

The input timing measurement block consists of the source timing measurement (STM) block and interrupt request (IRQ) controller. Input timing parameters are measured by the STM block and stored in registers. Some input conditions will generate an IRQ to an external micro-controller. The IRQ generating conditions are programmable.

2.4.1 Source Timing Measurement

When it receives the active CRT signal (R,G,B and Sync signals) the Source Timing Measurement unit begins measuring the horizontal and vertical timing of the incoming signal using the sync signals and TCLKi as a reference. Horizontal measurement occurs by measuring a minimum and a maximum value for each parameter to account for TCLKi sampling granularity. The measured value is updated every line. Vertical parameters are measured in terms of horizontal lines. The trailing edge of the Hsync input is used to check the polarity of the Vsync input. The table below lists all the parameters that may be read in the source timing measurement (STM) registers of the gmZAN1.

Table 11. Input Timing Parameters Measured by the STM Block

Parameter Unit Updated at:

HSYNC Missing N/A Every 4096 TCLKs and every 80ms (2-bits) VSYNC Missing N/A Every 80ms HSYNC/VSYNC Timing Change N/A When the horizontal period delta or the vertical

eriod delta to the previous line / frame exceeds the

threshold value (programmable). HSYNC Polarity Positive/Negative After register read VSYNC Polarity Positive/Negative Every frame Horizontal Period Min/Max TCLKs and SCLKs After register read HSYNC High Period Min/Max TCLKs After register read Vertical Period Lines Every frame VSYNC High Period Lines Every frame Horizontal Display Start SCLKs Every frame Horizontal Display End SCLKs Every frame Vertical Display Start Lines Every frame Vertical Display End Lines Every frame Interlaced Input Detect N/A Every frame CRC Data/Line Data N/A Every frame CSYNC Detect N/A Every 80ms

The display start/end registers store the first and the last pixels/lines of the last frame that have RGB data above a programmed threshold. The reference point of the STM block is the same as that of the source timing generator (STG) block:

z The first pixel: the pixel whose SCLK rising edge sees the transition of the HSYNC polarity from low to high. z The first line: the line whose HSYNC rising edge sees the transition of the VSYNC polarity from low to high.

The CRC data and the line data are used to detect a test pattern image sent to the gmZAN1 input port.

2.4.2 IRQ Controller

Some input timing conditions can cause the gmZAN1 chip to generate an IRQ. The IRQ-generating conditions are programmable, as given in the following table.

Table 12. IRQ-Generation Conditions

IRQ Event Remark

Timing Event One of the three events:

z Leading edge of Vsync input, z Panel line count (the line count is programmable), z Every 10ms

Only one event may be selected at a time.

Timing Change Any of the following timing changes:

z Sync loss, z DDS tracking error beyond threshold, z Horizontal/vertical timing change beyond threshold

Threshold values are programmable.

Reading the IRQ status flags will not affect the STM registers. Note that if a new IRQ event occurs while the IRQ status register is being read, the IRQ signal will become inactive for minimum of one TCLK period and then get re-activated. The polarity of the IRQ signal is programmable.

2.5.1 Scaling Filter

The gmZAN1 scaling filter uses an advanced adaptive scaling technique proprietary to Genesis Microchip Inc. and provides high quality scaling of real time video and graphics images. This is Genesis’ third generation scaling technology that benefits from the expertise and feedback gained by supporting a wide range of solutions and applications.

2.5.2 Gamma Table

The gamma table is used to adjust the RGB data for the individual display characteristics of the TFT panel. The overall gamma of the display may be set, as well as separate corrections for each of the three display channels. In addition, the gamma table may be used for contrast, brightness, and white balan ce (temperature) adjustments. The lookup table has an 8-bit input (256 differen t RGB entries) and produces a 10-bit output.

2.5.3 RGB Offset

The RGB offsets provide a simple shift (positive or negative) for each of the three color channels. This may be used as a simple brightness adjustment within a limited range. The data is clamped to zero for negative offsets, and clamped to FFh for positive offsets. This adjustment is much faster than recalculating the gamma table, and could be used with the OSD user controller to provide a quick brightness adjust. An offset range of plus 127*4 to minus 127*4 is available.

2.5.4 Panel Data Dither

For TFT panels that have fewer than eight bits for each R,G,B input, the gmZAN1 provides ordered and random dithering patterns to help smoothly shade colors on 6-bit panels.

2.5.5 Panel Background Color

A solid background color may be selected for a border around th e active display area. The background color is most often set to black.

2.6 Panel Interface

The gmZAN1 chip interfaces directly with all of today’s commonly used active matrix flat panels with 640x480, 800x600 and 1024x768 resolutions. The resolution and the aspect ratio are NOT limited to specific values.

2.6.1 TFT Panel Interface Timing Specification

The TFT panel interface timing parameters are listed in Table 13 below. Refer to three timing diagrams of Figure 7 and Figure 8 for the timing parameter definition. All aspects of the gmZAN1 interface are programmable. For horizontal parameters, Horizontal Display Enable Start, Horizontal Display Enable End, Horizontal Sync Start and Horizontal Sync End are programmable. Vertical Display Enable Start, Vertical Display Enable End, Vertical Sync Start and Vertical Sync End are also fully programmable. In order to maximize panel data setup and hold time, the panel clock (PCLKA, PCLKB) output skew is programmable. In addition, the current drive strength of the panel interface pins is programmable.

NOTE: Numbers in [ ] are for two pixels/clock mode. NOTE: The drive current of the panel interface signals is programmable as shown in Table 1. The drive current is to be

programmed through the API upon chip initialization. Output current is programmable from 2 mA to 20mA in increments of 2 mA. Drive strength should be programmed to match the load presented by the cable and input of the panel. Values shown are based on a loading of 20pF and a drive strength of 8 mA.

NOTE *1: The PCLK is the panel shift clock. NOTE *2: The DCLK stands for Destination Clock (DCLK) period. Is equal to:

-PCLK period in one pixel/clock mode,

-twice the PCLK period in two pixels/clock mode. NOTE *3: The setup/hold time spec. for PCLK also applies to PHS and PdispE. The setup time (t16) and the hold time (t17) listed

in this table are for the case in which no clock-to-data skew is added. The PVS/PHS/PdispE/Pdata signals are asserted on the rising edge of the PCLK. The polarity of the PCLK and its skew are programmable. Clock to Data skew can be adjusted in sixteen 800-ps increments. In combination with the PCLK polarity inversion, the clock-to-data phase can be adjusted in total of 31 steps.

NOTE *4: The polarity of the PCLKA and the PCLKB are independently programmable.

The micro controller must have all the timing parameters of the panel used for the monitor. The parameters are to be stored in a non-volatile memory. As can be seen from this table, the wide range of timing programmability of the gmZAN1 panel interface makes it possible to support various kinds of panels known today:

2.6.2 Power Manager

LCD panels require logic power, panel bias power, and control signals to be sequenced in a specific order, otherwise severe damage may occur and disable the panel permanently. The gmZAN1 has a built in power sequencer (Power Manager) that prevents this kind of damage. The Power Manager controls the power up/down sequences for LCD panels within the four states described below. See the timing diagram Figure 9.

2.6.2.1 State 0 (Power Off)

The Pbias signal and Ppower signal are low (inactive). The panel controls and data are forced low. This is the final state in the power down sequence. PM is kept in state 0 until the panel is enabled.

2.6.2.2 State 1 (Power On)

Intermediate step 1. The Ppower is high (active), the Pbias is low (inactive), and the panel interface is forced low (inactive).

2.6.2.3 State 2 (Panel Drive Enabled)

Intermediate step 2. The Ppower is high (active), the Pbias is low (inactive), and the panel interface is active.

2.6.2.4 State 3 (Panel Fully Active)

This is the final step in the power up sequence, with Ppower and Pbias high (active), and the panel interface activ e. PM is kept in this state until the internal TFT_Enable signal controlled by Panel Control register is disabled. The panel can be disabled through either an API call under program control or automatically by the gmZAN1 to prevent damage to the panel.

Figure 9. Panel Power Sequence

In Figure 9 above, t2=t6 and t3=t5. t1,t2,t3 and t4 are independently p rogrammable from one to eight steps in length. The length of each step is in the range of 511 * X* (TCLKi cycle) or (TCLKi cycle) * 32193 *X, where X is any positive integer value equal to or less than 256. TCLKi is the reference clock to the gmZAN1 chip, and ranges from

14.318 MHz to 50 MHz in frequency. This programmability provides enough flexibility to meet a wide range of power sequencing requirements by various panels.

2.6.3 Panel Interface Drive Strength

As mentioned previously, the gmZAN1 has programmable output pads for the TFT panel interface. Three groups of panel interface pads (panel clock, data, and control) are independently controllable and are programmed using API calls. See the API reference manual for details.

2.7 Host Interface

The host microcontroller interface of the gmZAN1 has two modes of operation: gmB120 compatible mode, and a 4bit serial interface mode. z GmB120 compatible mode-Four signals consisting of 1 data bit, a frame synchronization signal, a clock signal

and an Interrupt Request signal (IRQ). This mode is entered when a pull-down resistor is not connected to MFB6(pin number 106).

z 4-bit serial interface mode-Same as gmB120 compatible mode with the addition of three data bits so that four

data bits are transferred on each clock edge. This mode is entered when a (10K ohm) pull-down resistor is connected to MFB6(pin number 106).

When the chip is configured for 4-bit host interface, MFB9:7 are used as HDATA3:1 and HDATA is used as HDATA0. For instruction, Read Data, or Write Data, the data order is D3:0, D7:4, D11 :8, The burst mode operation then uses three clocks (instead of twelve) for each 12-bit data (or address) transmission.

In both modes, a reset pin sets the chip to a known state when the pin is pulled low. The RESETn pin must be low for at least 100ns after the CVDD has become stable (between +3.15V and +3.45V) in order to reset the chip to a known state.

The gmZAN1 chip has an on-chip pull-down resistor in the HFS input pad. No external pull-up is required. The signal stays low until driven high by the microcontroller.

2.7.1 Serial Communication Protocol

In the serial communication between the microcontroller and the gmZAN1, the microcontroller always acts as an initiator while the gmZAN1 is always the target. The following timing diagram describes the protocol of the serial channel of the gmZAN1 chip.

Figure 10. Timing Diagram of the gmZAN1 Serial Communication

Table 15 summarizes the serial channel specification of the gmZAN1. Refer to Figure 10 for the timing parameter definition.

Table 15. gmZAN1 Serial Channel Specification

Parameter Min. Typ. Max.

Word Size (Instruction and Data) --- 12 bits --HCLK low to HFS high (t1) 100 ns HFS low to HCLK inactive (t2) 100 ns HDATA Write to Read Turnaround Time (t3) 1 HCLK cycle 1 HCLK cycle HCLK cycle (t4) 100 ns Data in setup time (t5) 25 ns Data in hold time (t6) 25 ns Data out valid (t7) 5 ns 10

In the read operation, the microcontroller (Initiator) issues an instruction lasting 12 HCLKs. After the last bit of the command is transferred to the gmZAN1 on the 12 rising edge of HCLK at which point the gmZAN1 will start driving data. At the 13

clock, the microcontroller must stop driving data before the next

rising edge of HCLK, the

gmZAN1 will begin driving data.

Figure 11. Serial Host Interface Data Transfer Format

2 bits 10 bits 12 bits

Command Address Data

Command: 01 Write 00 = Read 1x = Reserved

Note that when the chip is configured for a 4-bit host interface, MFB9:7 are used as HDATA 3:1 and HDATA is used as HDATA0. The command and address information are transferred as Address 1:0+Command1:0, Address5:2 and Address9:6. The data information is transferred as Data3:0,Data 7:4, Data 11:8. Thus, in this mode the HDATA pin carries Command0, Address2, Address6, Data0, Data4 and Data8. On the gmZAN1 reference design board, the microcontroller toggles the HCLK and HDATA lines under program control. Genesis Microchip provides API calls to facilitate communication between the microcontroller and the gmZAN1. Refer to the API reference manual for details.

2.7.2 Multi-Function Bus (MFB)

The Multi-Function Bus provides additional 12 pins that are used as general purpose inp ut and output (GPIO) pins. Each pin can be independently configured as input or output. MFB pins 9 through 5 have special functions: z When a 10K ohm pull-down resistor is connected to MFB6 (MFB6 has an internal pull-up resistor) MFB9:7 are

used as host data bits HDATA3:1.

z When a 10K ohm pull-down resistor is connected to MFB5 (MFB5 has an internal pull-up resistor) a crystal can

be placed between XTAL and TCLK instead of using an external oscillator for the TCLK input.

Note that all pins on the multi-function bus MFB11:0 are internally pulled-up.

2.8 On-Screen Display Control

The gmZAN1 chip has a built-in OSD (On-Screen Display) controller with an integrated font ROM. The chip also supports an external OSD controller for monitor vendors to maintain a familiar user interface. The internal and external OSD windows may be displayed anywhere the panel Display Enable is active, regardless of whether the panel would otherwise display panel background color or active data.

2.8.1 OSD Color Map

Both the internal and external OSD display use a 16 location SRAM block for the color programming. Each color location is a twelve-bit value that defines the upper four bits of each of the 8 bit Red, Blue and Green color components as follows:

z D3:0 Blue; D7:4 of blue component of color z D7:4 Green; D7:4 of green component of color z D11:8 Red; D7:4 of red component of color

To extend the 4-bit color value programmed to the full 8 bits the following rule is applied: if any of the upper four color bits are a “1”, then R (G, B) data 3:0=1111b, otherwise R (G, B) data 3:0=0000b

2.8.2 On-Chip OSD Controller

The internal OSD uses a block of SRAM of 1536x12 bits and a ROM of 1024x12 bits. The SRAM is used for both the font data and the character-codes while the ROM is used to store the bit data for 56 commonly used characters. The font data is for 12 pixel x 18 line characters, one bit per pixel. The font data starts at address zero. The character-codes start at any offset (with an address resolution of 16) that is greater than the last location at which font data has been written . It is the programmer’s responsibility to ensure that there is no overlap between fonts and character-codes. This implementation results in a trade-off between the number of unique fonts on-screen at any one time and the total number of characters displayed. For example, one configuration would be 98 font maps (56 fonts in ROM and 42 fonts in SRAM) and 768 characters (e.g. in a 24x32 array).

The on-chip OSD of the gmZAN1 can support a portrait mode (in which the LCD monitor screen is rotated 90 degrees). In this portrait mode, all the fonts must be loaded in the SRAM, because the ROM stores fonts for a landscape mode (typical orientation) only. The font size in the portrait mode is 12 pixels by 12 lines. As is the case in landscape mode, the SRAM is divided into a font storage area and a character code storage area. For example, 64 fonts can be stored in RAM and an OSD window of 768 characters (such as 24x32) can still be displayed.

The first address of SRAM to be read for the first character displayed (upper left corner of window)is also programmable, with an address resolution of 16 (8-bits as the top bits of the 12-bit SRAM address). The charactercode is a 12-bit value used as follows:

z D6:0 font-map select, this is the top seven bits of the address for the first line of font bits z D8:7 Background color, 00=bcolor0, 01=bcolor1, 10=bcolor2, 11=transparent background z D10:9 Foreground color (0, 1, 2 or 3) z D11 Blink enable if set to 1, otherwise no blink

Although the OSD color map has room for sixteen colors, only seven are used by the internal OSD: three background colors and four foreground colors.

The blink rate is based on either a 32 or 64 frame cycle and the duty cycle may be selected as 25/75/50/50% or 75/25%. The 2-bit foreground and background attribu tes directly select the color (there is no indirect “look-up”, i.e. there is no TMASK function). The 2560 addresses of the ROM/SRAM are mapped as 10 segments of 256 contiguous addresses each, to the OSD memory page of 100h-1FFh in the host interface. A 4-bit register value selects the segment to map to the host R/W page.

The character cell height and width are programmable from 5-66 pixels or 2-65 lines. The X/Y offset of the font bitmap upper-left pixel relative to the upper-left pixel of the character cell is also programmable from 0-63 (pixels or lines). The OSD window height and width in characters/rows is programmable from 1-64.

The Start X/Y position for the upper left corner of the OSD window is programmable (in panel pixels and lines) from 0-2047. There is an optional window border (equal width on all four sides of the window) or a window shadow (the window bottom and right side) the border is a solid color that is selected by an SRAM location as RGB444. The border width may be set as 1, 2, 4 or 8 pixels/lines. These parameters are summarized in Figure 12 and Table 16. The Font Data D11:0 for each line is displayed with bit D11 first (leftmost) and D0 last. The reference point for the OSD start is always the upper left corner of the Panel display, which is the start (leading edge) of Panel Display Enable for both Horizontal and Vertical timing.

The OSD Window start position sets the location of the first pixel of the OSD to display, including any border. That is; if the border is enabled, the start of the character display of the OSD is offset from the OSD start position by the width/height of the border.

To improve the appearance and make it easy to find the OSD window on the screen, the user may select optional shadowing (3D effect). The “Shadow” feature operates in the same manner as in the B120; that is, it produces a region of half intensity (scaler data) pixels of the same width and height as the OSD window, but offset to the right and down by 8 pixels/lines (the border width setting has no effect). OSD foreground and background colors always cover the OSD window region of the “shadow”, but transparent background pixels in the OSD will show the half intensity panel data. Therefore, it is not recommended to use both the “shadow” feature and transparent background OSD pixels together. The ”shadow” does not The border and shadow are mutually exclusive, only one may be selected at a time.

The OSD window is not affected by the scaling operation. The size will stay the same whether the source input data is scaled or not.

change the intensity of any panel background color over which it may be located .

2.9 TCLK Input

The source timing is measured by using the TCLK input as a reference. Also, the reference clock to the on-chip PLLs are derived from the TCLK. It is therefore crucial to have a jitter-free clock reference. Table 19 shows the requirements for the TCLK signal.

Table 19. TCLK Specification

Frequency 20 MHz to 50 MHz Jitter 250 ps maximum Rise Time (10% to 90%) 5 ns Duty Cycle 40-60

There is also an option to use a crystal (instead of an oscillator) for the TCLK input. This option is selected by pulling down MFB5 and connecting the crystal between XTAL and TCLK.
