Figure 2-14. Reset Timing
After reset has completed, the following sequence of operations must be completed:
1. Write 01h to VBus register 0xB00060
2. Write 01h to VBus register 0xB00063
3. Write 00h to VBus register 0xB00060
2.12 Adjusting External Syncs
The TVP5160 decoder stores values for the positions of the external syncs for two different modes:
525-line with ITU-R BT.601 sampling
625-line with ITU-R BT.601 sampling
Once the values are stored, they are retained and restored when the signal switches back into one of
these two modes.
The proper sequence to change the external sync positions is:
To set NTSC, PAL-M, NTSC 443, PAL 60 (525-line modes):
– Make sure the standard is one of the above 525-line mode formats by forcing the video standard
– Set HS, VS, VBLK, and AVID external syncs (register 16h through 24h)
To set PAL, PAL-N, SECAM (625-line modes):
– Make sure the standard is one of the above 625-line mode formats by forcing the video standard
– Set HS, VS, VBLK, and AVID external syncs (register 16h through 24h)
Once programmed, the values for each mode are retained when the signal switches back into that or other
compatible video standards.
