10.3 Power Sleep Controller (PSC)
The Power Sleep Controller (PSC) includes a Global Power Sleep Controller (GPSC) and a number of Local Power
Sleep Controllers (LPSC) that control overall device power by turning off unused power domains and gating off
clocks to individual peripherals and modules. The PSC provides the user with an interface to control several
important power and clock operations.
For information on the Power Sleep Controller, see the Power Sleep Controller (PSC) for KeyStone Devices User
Guide in 2.6 ‘‘Related Documentation from Texas Instruments’’ on page 19.
10.3.1 Power Domains
The device has several power domains that can be turned on for operation or off to minimize power dissipation. The
Global Power Sleep Controller (GPSC) is used to control the power gating of various power domains.
The following table shows the 66AK2H14/12/06 power domains.
