Because the pin state changes occur at specific values of the
free-running counter, the pulse width can be controlled accurately to the
resolution of the free-running counter, independent of software
latencies. To generate an output signal of a specific frequency and duty
cycle, repeat this pulse-generating procedure.

After a match occurs, change the appropriate OC1D bit to the
opposite polarity, then add a value representing the width of the
pulse to the original value and write it to the output compare
register.
