9 / 19 page  VP5313/VP5513 8 RSTCTL Reset Data Control TSURST Soft reset control 0 Normal operation 1 Chip soft reset SC_ADJ Sub Carrier Adjust SC7-0 Sub carrier frequency seed value. FREQ2-0 Sub carrier frequency FR17-00 24 bit Sub carrier frequency programmed via I2C bus. FREQ3 is the MSB. SCHPHM-L Sub carrier phase offset SCH8-0 9 bit Sub carrier phase relative to the 50% point of the leading edge of the horizontal part of composite sync. SCHPHM bit 0 is the MSB. HSOFFL-M Horizontal Sync Output Offset HSOFF9-0 This is a 10 bit number which allows the user to offset the start of digital data input with reference to the pulse HS. SLAVE1-2 H & V Slave Mode Control NCORSTD NCO line reset disable NCO is always reset at end of 4(8) field sequence in NTSC(PAL) regardless of the value of this control bit 0 NCO is reset every line in NTSC mode 1 NCO line reset is disabled VBITDIS Ignore REC656 V-bit select 0 REC656 V-bit will be decoded and the line blanked accordingly 1 REC656 V-bit will be ignored VSMODE Select type of Vsync input 0 Standard Vsync I/P 1 Field even/odd Vsync I/P F_SWAP Invert field detect decision 0 Standard relationship applies 1 Inverted relationship applies SL_HS(1:0) Internal Hsync delay control 00 No internal delay 01 1 x 27MHz cycle delay 10 2 x 27MHz cycle delay 11 3 x 27MHz cycle delay TSLAVE2 HCNT(9:0) - Internal H counter is reset to this value on falling edge of Hsync input. TSTPAT Test Pattern Register TTX_PAT Teletext test pattern enable 0 Normal operation 1 Teletext test pattern enabled RAMPEN Modulated test ramp enable 0 Normal operation 1 Modulated test ramp enabled TTXLO2-0 Teletext Odd Line Enable L6-22 1 = Teletext Enabled on that line number TTXLE2-0 Teletext Even Line Enable L318-335 1 = Teletext Enabled on that line number TTXDD7-0 Teletext Request Pulse Position TTXCTL Teletext Control TTXEN Teletext enable 0 Teletext disabled 1 Teletext enabled CCREG1 Closed Caption register 1 F1W1D6-0 Field one (line 21), first data byte CCREG2 Closed Caption register 2 F1W2D6-0 Field one (line 21), second data byte CCREG3 Closed Caption register 3 F2W2D6-0 Field two (line 284), first data byte CCREG4 Closed Caption register 4 F2W2D6-0 Field two (line 284), second data byte CCCTL Closed Caption control register F1ST Field one (line 21) status bit 0 New data has been loaded to CCREG1-2 1 Data has been encoded F2ST Field one (line 284) status bit 0 New data has been loaded to CCREG3-4 1 Data has been encoded F1EN Closed Caption field one (line 21) 0 Disabled 1 Enabled F2EN Closed Caption field one (line 284) 0 Disabled 1 Enabled |
