the power management block 920 responsive to a real-time clock
circuit alarm and/or other conditions. It would appear
reasonable that a reactivation responsive to a real-time clock
may be considered a “wake-up event.”
The examiner further contends, referring to column 14, lines
64-66, and column 27, line 66 to column 28, line 2, of Walsh,
that the reference teaches the placement of the bus in a reduced
power consumption state. The cited portion of column 14 refers
to a “bus-quieting” mode for reducing system power consumption by
toggling data/address bus 104 only on bus transfers. The cited
portion of column 27 to column 28 refers to the state transition
diagram of Figure 23 depicting six states, “READY (0,0) state 0,
STANDBY (0,1) state 1, TEMPORARY state 2, 3V SUSPEND (1,0) state
3, 0-V SUSPEND (1,0) state 4, and OFF (1,1) state 5.” While
these portions refer to a reduction of system power consumption,
the instant claim calls for placing the bus in a reduced power
consumption state. Still, one may argue, reasonably, that if
system power consumption is reduced, then any system bus must
also be in a reduced power consumption mode, especially in view
of Walsh’s disclosure of a “bus-quieting” mode.
However, the instant claim does not merely require that the
bus be placed in a reduced power consumption state. It requires
