Narrative:

During initial climb out the ECAM indicated; autothrust disconnect; altitude law; and protections lost. We contacted departure control; climbed to 10000 ft as directed and asked for a vector to deal with our flight control issue. We cleaned up the aircraft in the climb. Ran the after takeoff checklist and the ECAM. The ECAM directed us to turn off and on the facility #1 and #2. We did that and recovered all system normally. We contacted maintenance and dispatch; explained our issue; and told them we planned to land back at den. We asked for and received vectors to a visual runway 16L at den. Landing and taxi in were uneventful.
