MTV130
GENERAL DESCRIPTION
MTV130 is designed for LCD monitor applications to display built-in characters or fonts onto an LCD monitor screens. The display operation occurs by transferring data and control information from the micro-controller to RAM through a serial data interface. It can execute full-screen display automatically, as well as specific functions such as character background, bordering, shadowing, blinking, double height and width, font by font color control, frame positioning, frame size control by character height and rowto-row spacing, horizontal display resolution, full-screen erasing, fade-in/fade-out effect, windowing effect, shadowing on window and full-screen self-test pattern generator. MTV130 provides true 512 fonts including 496 standard fonts and 16 multi-color fonts and 2 font sizes, 12x16 or 12x18 for more efficacious applications. So each one of the 512 fonts can be displayed at the same time. The full OSD menu is formed by 15 rows x 30 columns, which can be positioned anywhere on the monitor screen by changing vertical or horizontal delay.

3.0 FUNCTIONAL DESCRIPTIONS
3.1 SERIAL DATA INTERFACE
The serial data interface receives data transmitted from an external controller. And there are 2 types of bus can be accessed through the serial data interface, one is SPI bus and other is I2C bus. 3.1.1 SPI bus While SSB pin is pulled to "high" or "low" level, the SPI bus operation is selected. And a valid transmission should be starting from pulling SSB to "low" level, enabling MTV130 to receiving mode, and retain "low" level until the last cycle for a complete data packet transfer. The protocol is shown in Figure 1.

And a valid transmission should be starting from writing the slave address 7AH to MTV130. The protocol is shown in Figure 2.

Format (c) S - R - C - D D D D D D ..... Where S=Slave address, R=Row address, C=Column address, D=Display data Each arbitrary length of data packet consists of 3 portions viz, Row address (R), Column address (C), and Display data (D). Format (a) is suitable for updating small amount of data which will be allocated with different row address and column address. Format (b) is recommended for updating data that has same row address but different column address. Massive data updating or full screen data change should use format (c) to increase transmission efficiency. The row and column address will be incremented automatically when the format (c) is applied. Furthermore, the undefined locations in display or fonts RAM should be filled with dummy data. TABLE 1. The configuration of transmission formats. Address Row Address Bytes of Display Reg. Columnab Columnc Data Row Attribute Bytes of Display Reg.

There are 2 types of data should be accessed through the serial data interface, one is ADDRESS bytes of display registers, and other is ATTRIBUTE bytes of display registers, the protocol are same for all except the bit5 of row address and the bit5 of column address. The MSB(b7) is used to distinguish row and column addresses when transferring data from external controller. The bit6 of column address is used to differentiate the column address for format (a), (b) and format (c) respectively. Bit5 of row address for display register is used to distinguish ADDRESS byte when it is set to "0" and ATTRIBUTE byte when it is set to "1". And at address bytes, bit5 of column address is the MSB (bit8) and data bytes are the 8 LSB (bit7~bit0) of display fonts address to save half MCU memory for true 512 fonts. So each one of the 512 fonts can be displayed at the same time. See Table 1. And for format (c), since D8 is filled while program column address of address bytes, the continued data will be the same bank of upper 256 fonts or lower 256 fonts until program column address of address bytes again. The data transmission is permitted to change from format (a) to format (b) and (c), or from format (b) to format (a) and (c), but not from format (c) back to format (a) and (b). The alternation between transmission formats is configured as the state diagram shown in Figure 3.

3.2 Address bus administrator
The administrator manages bus address arbitration of internal registers or user fonts RAM during external data write in. The external data write through serial data interface to registers must be synchronized by internal display timing. In addition, the administrator also provides automatic increment to address bus when external write using format (c).
3.3 Vertical display control
The vertical display control can generates different vertical display sizes for most display standards in current monitors. The vertical display size is calculated with the information of double character height bit(CHS), vertical display height control register(CH6-CH0).The algorithm of repeating character line display are shown as Table 2 and Table 3. The programmable vertical size range is 270 lines to maximum 2130 lines. The vertical display center for full screen display could be figured out according to the information of vertical starting position register (VERTD) and VFLB input. The vertical delay starting from the leading edge of VFLB, is calculated with the following equation: Vertical delay time = ( VERTD * 4 + 1 ) * H TABLE 2. Repeat line weight of character CH6 - CH0 CH6,CH5=11 CH6,CH5=10 CH6,CH5=0x CH4=1 CH3=1 CH2=1 CH1=1 CH0=1

3.4 Horizontal display control
The horizontal display control is used to generate control timing for horizontal display based on double character width bit (CWS), horizontal positioning register (HORD) and HFLB input. A horizontal display line includes 360 dots for 30 display characters and the remaining dots for blank region. The horizontal delay starting from HFLB leading edge is calculated with the following equation, Horizontal delay time = ( HORD * 6 + 49) * P Where P = 1 XIN pixel display time
3.5 Display & Row control registers
The internal RAM contains display and row control registers. The display registers have 450 locations which are allocated between (row 0, column 0) to (row 14, column 29), as shown in Figure 4 and Figure 5. Each display register has its corresponding character address on ADDRESS byte, its corresponding background color, 1 blink bit and its corresponding color bits on ATTRIBUTE bytes. The row control register is allocated at column 30 for row 0 to row 14 of attribute bytes, it is used to set character size to each respective row. If double width character is chosen, only even column characters could be displayed on screen and the odd column characters will be hidden.

3.6 Character ROM
MTV130 character ROM contains 512 built-in characters and symbols including 496 standard fonts and 16 multi-color fonts. The 496 standard fonts are located from address 0 to 495. And the 16 multi-color fonts are located from address 496 to 511. Each character and symbol consists of 12x18 dots matrix. The detail pattern structures for each character and symbols are shown in "CHARACTERS AND SYMBOLS PATTERN" on page 18.
3.7 Multi-Color Font
The color fonts comprises three different R, G, B fonts. When the code of color font is accessed, the separate R/G/B dot pattern is output to corresponding R/G/B output. See Figure 6 for the sample displayed color font. Note: No black color can defined in color font, black window underline the color font can make the dots become black in color. The detail pattern structures for each character and symbols are shown in "CHARACTERS AND SYMBOLS PATTERN" on page 18.

3.8 Luminance & border generator
There are 3 shift registers included in the design which can shift out of luminance and border dots to color encoder. The bordering and shadowing feature is configured in this block. For bordering effect, the character will be enveloped with blackedge on four sides. For shadowing effect, the character is enveloped with blackedge for right and bottom sides only.

3.11 PWM D/A converter
MTV130
The encoder generates the video output to ROUT, GOUT and BOUT by integrating window color, border blackedge, luminance output and color selection output (R, G, B) to form the desired video outputs.
There are 4 open-drain PWM D/A outputs (PWM0 to PWM3). These PWM D/A converter outputs pulse width are programmable by writing data to Column 23 to 26 registers of Row 15 with 8-bit resolution to control the pulse width duration from 0/256 to 255/256. And the sampling rate is selected by (PWM1, PWM0) shown as table 5. In applications, all open-drain output pins should be pulled-up by external resistors to supply voltage (5V to 9V) for desired output range. b7 Column 23 | Column 26 MSB b6 b5 b4 b3 PWMDA0 | PWMDA3 b2 b1 b0
