8 / 21 page  ICS2008B 8 ICS2008B Rev D 4/05/05 Video Control Register IR32 GENLOCK ENABLE — When set to one, this bit enables the genlock circuits to sync to the selected video input signal. When reset to 0, the video sync will “freewheel,” generating video timing from the internal oscillator. The freewheel mode would be selected when striping LTC to allow synchroni- zation with a MIDI sequencer or other strictly timed audio source. VTRES — When set to one, this bit clears the video timing counters to dot zero of line 1 of field 1. This is useful when the video is free running, not genlocked and LTC sync needs to be synchronized to an event such as the CLICK input. VSYNCSEL — When set to one, this bit selects the video input source from Video2 (Y2) to be the SYNC source for the internal video timing. Otherwise, when reset to zero, Video1 (Y1) is selected. VITCSEL — When set to one, this bit selects the video input source from Video2 (Y2) to be the VITC time code source for the VITC receiver. Otherwise, when reset to zero, Video1 (Y1) is selected. VOUTSEL — When set to one, this bit selects the video input source from Video2 (Y2, C2) to be output on the video outputs (YOUT, COUT). When reset to zero, Video1 (Y1, C1) are selected. VID1_S — When set to one, this bit causes the Video1 source to be treated as S-Video. Otherwise, when cleared to zero, the Video1 source is treated as composite video. VID2_S — When set to one, this bit causes the Video2 source to be treated as S-Video. Otherwise, when cleared to zero, the Video2 source is treated as composite video. VITC Read Line Select Registers IR30-IR31 As with the VITC Write Line Register, these registers allow control of the individual redundant VITC read lines. The processor can also reprogram these dynamically to allow for scanning of VITC code when the source lines are unknown. Read Line – Selects the line from which VITC code is to be read within each field. It works identically to the Write Line in that the video line selected is the number in this register plus 10. Auto line scanning is enabled by writing a 1Fh to the Read Line field. This causes the VITC reader to search for time code. If VITC Read Line 1 is set to search, it starts with line 10 and quits when it finds a valid time code or when it reaches line 41. Searching with VITC Read Line 2 starts after VITC Read Line 1. In the case of searching for both VITC Read Lines 1 and 2, VITC Read Line 2 starts searching after the first valid time code has been found. However, if VITC Read Line 1 is set to a specific line, VITC Read Line 2 starts after that specified line regardless of whether valid time code was received. In any case, the search terminates after line 41. CRCERR — This bit is reset to zero when a valid VITC code has been received. It is valid from the end of the selected video line until the end of the selected line in the next field. NOCODE — This bit is set when a framing error occurs in the VITC code, i.e. not all the bits of the code were received by the time the end of the video line occurred. Both CRCERR and NOCODE must be zero to qualify a VITC code.
