We haven't documented them yet. =) But here they are:
All ChucK programs are type-checked and emitted into
byte-code consisting of the following, which are really no
different than native machine instructions. At the end, there
is an example of a ChucK program and the corresponding
ChucK VM program.

The VM uses two stacks for each concurrent shred: one for memory
and one as registers. Also note the operations dealing with time.
One the reasons we implemented the VM with such an IS is so we
may later optimize and also replace sections of code at runtime.
Though the interface needs inventing, on-the-fly byte-coding is
very possible in the current VM.
