4/18 MTV121 revision 5.0 06/29/1999 MTV121 myson technology there are three transmission formats shown as below: format (a) r - c - d ? r - c - d ? r - c - d format (b) r - c - d ? c - d ? c - d ? c - d format (c) r - c - d ? d ? d ? d ? d ? d where r=row address, c=column address, d=display data 3.1.2 i 2 c bus i 2 c bus operation is only selected when ssb pin is left floating. and a valid transmission should be starting from writing the slave address 7ah, which is mask option, to MTV121. the protocol is shown in figure2. there are three transmission formats shown as below: format (a) s - r - c - d ? r - c - d ? r - c - d format (b) s - r - c - d ? c - d ? c - d ? c - d 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. there are 2 types of data should be accessed through the serial data interface, one is address bytes of dis- play registers, and other is attribute bytes of display registers, the protocol are same for all except bit5 of row 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". see table 1 on page 4. ms b lsb ssb sck sda first byte last byte figure 1. data transmission protocol (spi) figure 2. data transmission protocol (i 2 c) sck sda first byte ?@?@?@?@ ?@ start ack second byte last byte ack stop b7 b6 b0 b7 b0
5/18 MTV121 revision 5.0 06/29/1999 MTV121 myson technology the data transmission is permitted to change from format (a) to format (b) and (c), or from format (b) to format (a), but not from format (c) back to format (a) and (b). the alternation between transmission formats is config- ured as the state diagram shown in figure3. 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 inter- nal display timing. in addition, the administrator also provides automatic increment to address bus when exter- nal 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), verti- cal 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. table 1. the configuration of transmission formats. address b7 b6 b5 b4 b3 b2 b1 b0 format address bytes of display reg. row 1 0 0 x r3 r2 r1 r0 a,b,c column ab 0 0 x c4 c3 c2 c1 c0 a,b column c 0 1 x c4 c3 c2 c1 c0 c attribute bytes of display reg. row 1 0 1 x r3 r2 r1 r0 a,b,c column ab 0 0 x c4 c3 c2 c1 c0 a,b column c 0 1 x c4 c3 c2 c1 c0 c initiate row col c col ab da c da ab 1, x 0, 1 0, 0 x, x x, x 0, 1 1, x 1, x format (a) format (b) format (c) x, x 0, x input = b7, b6 0, 0 figure 3. transmission state diagram
6/18 MTV121 revision 5.0 06/29/1999 MTV121 myson technology 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 where h = one horizontal line display time note:" v " means the nth line in the character would be repeated once, while " - " means the nth line in the character would not be repeated. 3.4 horizontal display control the horizontal display control is used to generate control timing for horizontal display based on double char- acter width bit (cws), horizontal positioning register (hord), horizontal resolution register (horr), and hflb input. a horizontal display line consists of (horr*12) dots which include 360 dots for 30 display char- acters and the remaining dots for blank region. the horizontal delay starting from hflb leading edge is calcu- lated 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 figure4. 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, 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. table 2. repeat line weight of character ch6 - ch0 repeat line weight ch6,ch5=11 +18*3 ch6,ch5=10 +18*2 ch6,ch5=0x +18 ch4=1 +16 ch3=1 +8 ch2=1 +4 ch1=1 +2 ch0=1 +1 table 3. repeat line number of character repeat line weight repeat line # 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 +1 - - - - - - - - v - - - - - - - - - +2 - - - - v - - - - - - - v - - - - - +4 - - v - - - v - - - v - - - v - - - +8 - v - v - v - v - v - v - v - v - - +16 - v v v v v v v v v v v v v v v v - +17 v v v v v v v v v v v v v v v v v - +18 v v v v v v v v v v v v v v v v v v
