  Nonsense, there's nothing to it.  The AVR/ATMEGA parts have a single
match register that is used to compare against the PWM timer to
determine duty cycle.  Set your prescale to get the frequency that you
want (usually around 1KHz) and connect the PWM output as you need for
the type of drive that you want: locked-antiphase or sign/magnitude. 
Google is your friend, it can find many examples of what I just tersely
described.
