LOOP CONTROL
Pattern generator commands can be looped using the LOOP
bit (D1) in Pattern gen ctrl register (11H). If LOOP=1 the pro-
gram will be looped from the command 8 register or if there
is 0000 0000 and 0000 0000 in one command register. The
loop will start from command 1 and continue until stopped by
writing rgb_start=0 or loop=0. The example of loop is shown
in following figure:
30008523
SINGLE PROGRAM
If control bit LOOP=0 the program will start from Command 1
and run to either last command or to empty “0000 0000 / 0000
0000” command.
30008524
The LEDs maintain the brightness of the last command when
the single program stops. Changes in command register will
not be effective in this phase. The RGB_START bit has to be
toggled off and on to make changes effective.
START BIT
Pattern_gen_ctrl
register’s RGB_START bit will enable
command execution starting from Command 1.
Pattern gen ctrl register (11H)
rgb_start
Bit 2
0 – Pattern generator disabled
1 – execution pattern starting from command 1
0 – pattern generator loop disabled (single pattern)
1 – pattern generator loop enabled (execute until stopped)
0 – color intensity mode 0
1 – color intensity mode 1
