Feature description
DG: gradual outputs delay
This feature prevents large inrush current and reduces the bypass capacitors.
The fixed delay time can be activated with DG = LOW and the typical output delay is 30 ns
for each group of 8 outputs R, G, B. E.g.: R1, G1, B1 has no delay, R2, G2, B2 has 30 ns
delay and R3, G3, B3, has 60 ns delay, etc.
