Basic PWM programming
The PWM controllers are capable of generating the following brightness patterns:
Figure 11. Pulses with programmable brightness, ON/OFF period and repetition
The registers need to be programmed for this sequence:

On period = Period 0[1:0] * Time Unit [3:0]
Off period = Period 1[1:0] * Time Unit [3:0]
Duty cycle during on period = Brightness [7:4]
Number of cycles = Repetition [3:0]
Ramp-mode is disabled
