Adjusting External Syncs
The proper sequence to program the following external syncs is:
To set NTSC, PAL-M, NTSC 443, PAL60 (525-line modes):
Set the video standard to NTSC (register 02h)
Set HSYNC, VSYNC, VBLK, and AVID external syncs (registers 16h through 24h)
To set PAL, PAL-N, SECAM (625-line modes):
Set the video standard to PAL (register 02h)
Set HSYNC, VSYNC, VBLK, and AVID external syncs (registers 16h through 24h)
For autoswitch, set the video standard to autoswitch (register 02h)
2.10 Internal Control Registers
The TVP5146M2 decoder is initialized and controlled by a set of internal registers that define the operating
parameters of the entire decoder. Communication between the external controller and the TVP5146M2
decoder is through a standard I2C host port interface, as described earlier. Table 210 shows the summary
of these registers. Detailed programming information for each register is described in the following sections.
Additional registers are accessible through an indirect procedure involving access to an internal 24-bit address
wide VBUS. Table 211 shows the summary of the VBUS registers.
NOTE: Do not write to reserved registers. Reserved bits in any defined register must be written
with 0s, unless otherwise noted.
