LED Driver IC ——— EXC2668L
FUNCTIONAL DESCRIPTION
A command is the first byte (b0 to b7) inputted to EXC2668 via the DIN Pin
after STB Pin has changed from HIGH to LOW State. If for some reason the STB Pin
is set to HIGH while data or commands are being transmitted, the serial
communication is initialized, and the data/commands being transmitted are
considered invalid.
(1) Display Mode Setting Commands:
EXC2668 provides 2 display mode settings as shown in the diagram below: As stated earlier
a command is the first one byte (b0 to b7) transmitted to EXC2668 via the DIN Pin when STB is
LOW. However, for these commands, the bit 3 to bit 6 (b2 to b5) are ignored, bit 7 & bit 8
(b6 to b7) are given a value of 0.
The Display Mode Setting Commands determine the number of segments and grids to be
used(12 to 14segments, 4 to 6 grids). A display command ON must be executed in order to resume
display. If the same mode setting is selected, no command execution is take place,therefore, nothing
happens.

When Power is turned ON, the 7-grid , 11-segment modes is selected.
(2) Data Setting Commands
The Data Setting Commands executes the Data Write or Data Read Modes for EXC2668. The
data Setting Command, the bits 5 and 6 (b4, b5) are ignored, bit 7 (b6) is given the value of 1
while bit 8 (b7) is given the value of 0. Please refer to the diagram below.
When poweris turned ON, bit 4 to bit 1 (b3 to b0) are given the value of 0.
