2.6.4
When SCLK is used, the TVP3030 supports the special clocking requirements of some VRAM devices. For
example, some VRAM devices require the first SCLK pulse to occur during blank between the split shift
register transfer (SSRT) and the full shift register transfer VRAM operations. When SCLK mode is enabled
(TCR5 = logic 1) and blank is active, a high pulse on the SFLAG input is passed directly to the SCLK output.
If the high pulse on SFLAG is detected at any time during blank, the first SCLK pulse normally generated
after coming out of blank is suppressed. This is because the SSRT operation leaves the first pixel group of
the new line on the pixel bus as opposed to the last pixel group of the previous line. Figure 2–7 shows the
SCLK timing mode with the first SCLK pulse relocated. If this function is not used, the SFLAG terminal should
be connected to GND.
