11.8 Power Management
Power Management, as a defined class of functions, consists of mechanisms in
software and hardware to minimize system power consumption, manage system
thermal limits, and maximize system battery life. The RS8234 supports Power
Management on the PCI bus according to the PCI Bus Power Management
Interface Specification, Revision 1.0.

D3, of the PCI Bus Power Management Interface Specification. D0 is the
maximum powered state (on) and D3 is the minimum powered state (off). When
in the D3 state, SYSCLK is turned off.
