When using the I2C serial interface, the per-string LED current is changed from the full-scale value by programming the

STRn register, where n is the LED string number from 0 to 15. The ISTRn 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:

STRn = ISTR_FULL

ISTRn+1

where I

SRTn is the current of LED string n, ISTR_FULL is the full-scale LED current set by S2, and ISRTn is the value of the

current setting register for string n between 0 and 64 (0x3F).
