10.11 Preloaded Emulation Time-out

Configuration Registers

The Preloaded Emulation Time-out Configuration reg-

isters control the tEM_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.
