In addition to the four states implemented in the Pentium® Pro, the Pentium® II processor (as well as the Pentium® III and Pentium® 4) implemented two more states and another pin related to power conservation (the SLP# input pin—Sleep). The additional power conservation states are:
The Sleep state.
The Deep Sleep state.
The sections that follow provide a detailed description of the six power conservation states. Refer to Figure 27-1 on page 685 during the discussion of the power conservation states.
