When using the I 2 C serial interface, the per-string LED current is changed from the full-scale value by programming the
I STRn register, where n is the LED string number from 0 to 15. The I STRn register is a 6-bit word that sets the LED current
for each LED string to one of 64 linear levels. The per-string LED current is:
I STRn = I STR_FULL
ISTRn+ 1
64
,
where I SRTn is the current of LED string n , I STR_FULL is the full-scale LED current set by S2, and ISRT n is the value of the
current setting register for string n between 0 and 64 (0x3F).
