DESCRIPTION
It indexes the power budgeting data reported through the data register.
When 00h, it selects D0 Max power budget
When 01h, it selects D0 Sustained power budget
Other values would return zero power budgets, which means not supported
Reset to 00h.
Reset to 000000h.
DESCRIPTION
It specifies the base power value in watts. This value represents the required
power budget in the given operation condition. The default value may be
changed by auto-loading from EEPROM.
Reset to 04h.
It specifies the scale to apply to the base power value. The default value may
be changed by auto-loading from EEPROM.
Reset to 00b.
It specifies the power management sub state of the given operation condition.
It is initialized to the default sub state.
Reset to 000b.
It specifies the power management state of the given operation condition.
It defaults to the D0 power state. The default value may be changed by
auto-loading from EEPROM.
Reset to 00b.
It specifies the type of the given operation condition.
It defaults to the Maximum power state. The default value may be changed by
auto-loading from EEPROM.
Reset to 111b.
It specifies the power rail of the given operation condition.
Reset to 010b.
Reset to 0.
DESCRIPTION
When set, it indicates that the power budget for the device is included within
the system power budget. The default value may be changed by auto-loading
from EEPROM.
