Avoiding wash sales when options involved?

On March 29th I purchased shares in a stock, then through March i wrote covered calls based on that position.

Now, however, I want to unwind my position. I have not bought or sold any of the stock, but I did sell the covered calls and buy to close them.

My question is, does the wash sale timer start with the purchase of the underlying stock, or is it reset with me selling the covered calls?
