Dlm85.rst153 driven by a 22.5 kHz clock. This is a global mode, not per-PWM output,
154 which means that setting any PWM frequency above 11.3 kHz will switch
155 all 3 PWM outputs to a 22.5 kHz frequency. Conversely, setting any PWM
156 frequency below 11.3 kHz will switch all 3 PWM outputs to a frequency
157 between 10 and 100 Hz, which can then be tuned separately.
179 The LM96000 supports additional high frequency PWM modes (22.5 kHz, 24 kHz,
180 25.7 kHz, 27.7 kHz and 30 kHz), which can be configured on a per-PWM basis.
