The Preloaded Emulation Time-out Configuration reg-
isters control the t_{EM_TIMEOUT} setting that is applied
whenever the indicated preloaded charger emulation
profile is applied during the DCE Cycle. These settings
are not used if the EM_TO_DIS bit is set.
The contents of this registers are retained in Sleep.
