Basic PWM programming

Doc ID 16174 Rev 4

45/85

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
