I do not think there is a law that covers this question specifically. An employer can call you at home. the subject matter of the conversation may or may not be covered by a labor or employment law, but that is not the basis of your question.
Assuming that your boss is not calling to harass you for an illegal purpose, I don't see any legal recourse for you. For instance, if your boss is not calling to harass you based on your gender, religion, race, or other protected characteristic, her conduct most likely does not constitute illegal "harassment" under federal anti-harassment law.
In other words, I'm sad to say, your boss is free to be a jerk to you, as long as she isn't doing so for an illegal purpose.
