— If the break event is not masked, the target core enters the core C0 state and

the processor enters package C0.

— If the break event is masked, the processor attempts to re-enter its previous

package state.

•

If the break event was due to a memory access or snoop request.
— But the platform did not request to keep the processor in a higher package

Cstate, the package returns to its previous C-state.

— And the platform requests a higher power C-state, the memory access or snoop

request is serviced and the package remains in the higher power C-state.
