PWM is individually controlled by registers PWM0 to
PWM15
GSC low- and high-frequency fault detection is disabled
Over-temperature derating of LED strings is disabled
PHI input falling edge synchronizes LED PWM
Global intensity control uses GINT register
GSC input is divided by value of GSC prescaler register
External GSC signal at GSC input pin is used
External PHI signal at PHI input pin is used
PWM input pin is unused
