Although disabled, internal PHI
Frequency f PGEN = 20MHz / (8 * (10416 + 1)) = 240Hz
PHI multiplier = 1 (register setting + 1)
Although disabled, PHI maximum count = 4148
PWM operation enabled
Individual LED string drive pulse widths internally
determined
PWM input does not gate the output of the PWM engine
String on times allowed to extend beyond end of PWM
frame String on times allowed to extend into frame zero
Alternate timing not used
Global intensity (GINT) disabled
Although disabled, (GINT + 1) is provided to the
PWM engine
String drive phasing enabled
Delayed string turn on beginning after PWM
frame allowed
Delayed turn on occurring in frame zero allowed
Alternate timing not selected by PWM input state
Global intensity set to (127 + 1) / 255 = 50.2%
Alternate global intensity set to (95 + 1) / 255 = 37.6%
Strings current set at 50% of R S setting
All strings phase delay = zero
All strings assigned to FBO1
