The SC2200 supports up to three power planes. Three sig-
nals are used to control these power planes. Table 6-6
describes the signals and when each is asserted.
These signals allow control of the power of system devices
and the SC2200 itself. Table 6-7 describes the SC2200
power planes with respect to the different Sleep and Global
states.
The SC2200 power planes are controlled externally by the
three signals (i.e., the system designer should make sure
the system design is such that Table 6-7 is met) for all sup-
ported Sleep states.

The SC2200 supports power management events that can
manage:
• Transition of the system from a Sleep state to a Work
• Enabled wakeup events to set the WAK_STS bit
• Generation of an interrupt. This invokes the relevant
Table 6-8 lists the power management events that can gen-
erate an SCI or SMI.
