All strings set to zero phase delay with strings assigned as follows: FBO1: All Strings;
Although disabled, internal PHI frequency = 20MHz / (8 * (10416 + 1)) = 240Hz
Although disabled, internal GSC frequency = 20MHz / (80 + 1) = 246.914 kHz
Device awake, String current foldback disabled, String short circuit delay = 8µs
PWM overflow, GINT plus one, Phase delay and PWM operation enabled
PWM duty cycle = programmed value during initial calibration
Although disabled, GSC max count is set to 174 clock cycles
String short, string open and FBO open circuit faults enabled
GSC synchronized to the falling edge of an external signal
PHI synchronized to the falling edge of an external signal
Global intensity set to (2047 + 1) / 4096 = 50.00%
Global intensity set to (4095+ 1) / 4096 = 100%
All strings set with PWM value = 512 GSC cycles
All strings set with PWM value = 256 GSC cycles
