Transition time TT is duration of transition from the previous RGB value to programmed new value. Transition

times are defined as follows:

TT [2:0]

Transition time, ms

000

001

010

110

011

221

100

442

101

885

110

1770

111

3539

The figure below shows an example of RGB CET and TT times.

The command execution time also may be less than the transition time – the figure below illuminates this case.

LOOP CONTROL (1.65V

≤ VDDIO ≤ VDD1,2V) (unless otherwise noted)

Pattern generator commands can be looped using the LOOP bit (D1) in Pattern gen ctrl register (11H). If

LOOP=1 the program 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:
