When IS31FL3194 operates in Current Level Mode,
the value of Current Level Registers will decide the
output current of OUTx in 256 levels.
The output current may be computed using the
Formula (1):
7
0
2*][
256
n
n
MAX
OUT
nD
I
I (1)
Where D[n] stands for the individual bit value, 1 or 0,
in location n.
For example: if D7:D0 = 10110101,
I
OUT
= I
MAX
(2
7
+2

)/256
I

is set by Current Band Register.

Color Setting Registers store the color setting for
each output in Pattern Mode. Check Pattern Color
Setting section for more information about the color
setting registers.
Need to write Color Update Register (40h) to update
the data.
