I'd say it's a discrete digital oscillator. The only part that's analog is the Pulse output, derived from the ramp/triangle in the usual style. The other waveforms are generated directly by the 8-bit DAC, and that makes them digital.
For me, a DCO has digital timing and analog waveform creation.

But I don't much care what we call it as long as I can understand it!!
