Figure 8.
Latch and output enable are level sensitive and are not synchronized with rising-or-falling
edge of CLK signal.
When LE\DM terminal is low level, the latch circuit hold previous set of data.
When LE\DM terminal is high level, the latch circuit refresh new set of data from SDI chain.
When either OE-R\DM, OE-G, OE-B terminals are at low level, output terminals R\G\B1 to
R\G\B8 respond to the data, either ON or OFF.
When either OE-R\DM, OE-G, OE-B terminals are at high level, it switches off all the data on
the output terminal R\G\B1 to R\G\B8.
This device can customize the RGB sequence serial data flow by mean of setting DF0 and
DF1 (refer to
OUTXX assigned to the following: OUT0-2 -> R1, G1 and B1; OUT3-5 -> R2, G2 and B2,
OUT21-23 -> R8,G8 and B8.
