COMMAND EXECUTION TIME (CET) AND TRANSITION TIME (TT)
The command execution time CET is the duration of one sin-
gle command. Command execution times are defined as
follows, when RT=82kΩ:
CET [3:0]
CET duration, ms
CET [3:0]
1110
1111
CET duration, ms
2949

Transition time TT is duration of transition from the previous
RGB value to programmed new value. Transition times are
defined as follows:
0010
0011
0100
0101
