RESOLUTION
External resistors set maximum current for each LED string, up to at least 500mA
6-bit ISTR registers reduce string current from maximum set by global resistor
6-bit GINT register or PWM input (accepts 20Hz To 50kHz, 0% to 100% duty cycle)
8-bit PWM registers set individual string pulse width
6-bit temperature pulse width derating individually applied to each string
10-bit LED string pulse width computed from global and individual pulse width settings
