// Arguments: (0)
// None
// Return Value:
// An Integer containing a device status bitmap:
// Bit 0 - Set if the device is present.
// Bit 1 - Set if the device is enabled and decoding its resources.
// Bit 2 - Set if the device should be shown in the UI.
// Bit 3 - Set if the device is functioning properly (cleared if device failed its diagnostics).
// Bit 4 - Set if the battery is present.
// Bits 5-31 - Reserved (must be cleared).

//
// Conveys the temperature of a device's internal temperature sensor to the platform when a temperature trip point
// is crossed or when a meaningful temperature change occurs.

// Arguments: (1)
// Arg0 - An Integer containing the current value of the temperature sensor (in tenths Kelvin)
