required on SCLK so that it can drive a larger load, a similar buffer can be placed on RCLK to match the
signal delay before connecting to LCLK. However, the delay from LCLK to RCLK cannot exceed one RCLK
period –7 ns, (see the timing-parameter specifications for more details).
When the VRAM split shift register operation is performed (see Figure 2–3 and Figure 2–4), the SCLK timing
is adjusted to work with the SFLAG input. Basically, the split shift register operation inserts an SCLK during
the blank period. This causes the first group of pixel data to appear at the pixel port during blank and allows
the first group of data to be displayed as soon as the palette comes out of blank. Figures 2–3 and 2–5 show
the case when the SSRT (split shift register transfer) function is enabled. When a rising edge occurs on the
SFLAG input, one SCLK with a minimum 15-ns pulse duration is generated after the specified delay. Since
this is designed to meet VRAM timing requirements, the SSRT-generated SCLK replaces the first SCLK in
the regular shift register transfer case as described above (see Section 2.15 for a detailed explanation of
the SSRT function).
