5.1. Horizontal Timing
Each scan line contains hn pixels as shown in Figure 12. Of the hn pixels, only (hn - hblk) pixels are displayed. The
AV signal is used to indicate the active portion of the horizontal scan line. The Horizontal Blank portion actually
consists of three parts: Horizontal Front Porch, Horizontal Sync, and Horizontal Back Porch. The KS0119 outputs
the Horizontal Sync signal to the display monitor.
In Master mode, the NTSC Encoder generates the AV signal. AV can be used by the external frame buffer to control
the pixel read out. Because of the memory access latency associated with the external memory subsystem, AV
should lead the pixel data by n pixel clocks. This is done by controlling the hav parameter. All horizontal timing
parameters are programmable and Table 5 contains the information on how to calculate the line timing control
register values for both NTSC and RGB displays.
Figure 12. Horizontal Timing
*: This number is not used to control the Horizontal Sync Tip in NTSC mode.
5.2. Vertical Timing
Each field contains the active line and vertical blank portions. The vertical blank portion is further divided into Vertical
Front Porch, Verical Sync, and Vertical Back Porch.There are four parameters that control the vertical timing: VFP,
VSYN, VBLK, and VN. They are specified in terms of lines. Figure 13 shows the timing related to the four
parameters. For NTSC output, these parameters are fixed and the power on default values should be used.
However, if the
BLKALL
bit in the
Command
Register
is set to 1, the
VBLK
value will be used instead. Table 6
provides information on how to program these parameters.
