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