Figure 12 shows an example of the effect of the output gradual delay on the RED color

group outputs.

Data flow management (CFG 9-CFG 11)

The 8x3 shift registers have a default RGB sequence serial data flow according to the table

shown into the configuration register (bit CFG-9, CFG-10 and CFG-11). Figure 13 shows

how serial data are loaded in accordance with the data flow sequence selected through the

configuration register. The default sequence is RGB (first bit will be R8, last bit B1 then: R8-

R1, G8-G1, B8-B1).
