The pin assignment above applies to X15 and X16.
The output frequency and the duty cycle can be varied over a wide
range. In practical operation, only one of the two quantities will be
varied - the other quantity will remain unvaried.

Example: The desired analog value (demand engine speed of 900 –
8000 rpm) is mapped to a duty-cyle range of 5 % to 95 %. The
frequency is set at 1 kHz.
Example: The desired output quantity (demand torque of 20 – 200
Nm) is mapped to a frequency range of 200 Hz to 2000 Hz. The duty
cycle is always 50 %.
