11 / 22 page FUNCTIONAL DESCRIPTION (continued) IV - I 2C Bus Register Map (continued) IV.1 - Registers Functions (continued) Register Function Bit(s) Description R7 Address 07H Display mode BOX ON 0, 1-23,24 (D0, D1, D2) The “boxing” function is enabled on row 0,1-23 and 24 by D0, D1 and D2 set to one. TOP / BOTTOM Single / Double Height (D4/D3) X0 = Normal 01 = double height Rows 0 to 11 11 = double height Rows 12 to 23 Conceal / Reveal (D5) Conceal Reveal Function Cursor ON/OFF (D6) Cursor position given by row/column value of R9/R10 STATUS ROW BTM / TOP (D7) The row 24 is displayed before the “Main text Area” (lines 0-23) or after (D7 = 0). R8 Memory access VPS Enable (D4) D4 = 1 Enable VPS acquisition and DV signal output. Clear Memory (D3) D4 = 1 Clear memory. Chapter selected with A2A1A0 (D2, D1, D0) R4. Chapter Address (D2, D1, D0) Chapter selection R9 to R11A Address 08H to 0BH* Active row address (R9), active column address (R10). Data contained in R11A read (written) from (to) memory by microprocessor via I 2C. R11B Address 0BH* Status VCS QUAL (D0) Good VCS quality signal detected (D0 = 1). Bad VCS quality signal detected (D0 = 0). DATA QUAL (D1) Good TELETEXT signal (D1 = 1). Bad TELETEXT signal (D1 = 0). 50/60Hz (D7) If D1 = 0 frame frequency is 50Hz (only valid with good VCS) * Reading of R11A or R11B is de termined by register 0, bit D0. However, write operation is a lways performed on R11A register. START COLUMN PRD4 PRD3 PRD2 PRD1 PRD0 0 Do care magazine HOLD MAG2 MAG1 MAG0 1 Do care page tens PT3 PT2 PT1 PT0 2 Do care page units PU3 PU2 PU1 PU0 3 Do care hours tens X X HT1 HT0 4 Do care hours units HU3 HU2 HU1 HU0 5 Do care minutes tens X MT2 MT1 MT0 6 Do care minutes units MU3 MU2 MU1 MU0 The abbreviations have the same significance as in Table 1 with the exception of the “DO CARE” entries. It is only when this bit is “1” that the corresponding digit is taken into consideration on page request. For example, a page defined as ”normal” or one defined as “timed” may be selected. If “HOLD” is low the page is held. The addressing of successive bytes via the I 2C is automatic. Table 4 : Register R3 V - Character Sets The complete character set with 8-bit decoding is given in Table 5. Characters in columns 0 and 1 are normally dis- played as blanks. Black dots represent the charac- ter shape whereas white dots represent the background. Each character can be identified by a pair of corre- sponding row and column integers : for example the character “3” may be indicated by 3/3. A rectangle may be represented as follows : The characters 8/6, 8/7, 9/5, 9/7 are used as spe- cial characters, always in conjunction with 8/5. The 13 national characters are placed in columns with bit 8 = 0. STV5347 - STV5347/H - STV5347/T 11/22 |
