If the SSRT function is enabled but SFLAG is held low, the SCLK runs as if the SSRT function is disabled.
Since the SFLAG input is not qualified by the BLANK signal within the palette, it needs to be held low or
disabled any time the SSRT SCLK pulse is not intended. Refer to Section 2.3 and Figures 2–2 through 2–5
for more system details.
