88 / 114 page  Programmable USB Port Power Controller with Charger Emulation Datasheet Revision 1.4 (07-16-13) 88 SMSC UCS1002 DATASHEET ‘1’ - The Legacy 4 charger emulation profile is not enabled. Bit 2 - LG3_EM_DIS - Disables the Legacy 3 charger emulation profile. ‘0’ (default) - The Legacy 3 charger emulation profile is enabled. ‘1’ - The Legacy 3 charger emulation profile is not enabled. Bit 1 - LG2_EM_DIS - Disables the Legacy 2 charger emulation profile. ‘0’ (default) - The Legacy 2 charger emulation profile is enabled. ‘1’ - The Legacy 2 charger emulation profile is not enabled. Bit 0 - LG1_EM_DIS - Disables the Legacy 1 charger emulation profile. ‘0’ (default) - The Legacy 1 charger emulation profile is enabled. ‘1’ - The Legacy 1 charger emulation profile is not enabled. 10.11 Preloaded Emulation Timeout Configuration Registers The Preloaded Emulation Timeout Configuration registers 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_TIMEOUT_DIS bit is set. 10.11.1 BCS Emulation Timeout Config - 22h The contents of this register are retained in Sleep. Bits 5 - 4 - DCP_EM_TIMEOUT[1:0] - Defines the tEM_TIMEOUT setting, as shown in Table 10.24, that is applied when the BC1.2 DCP charger emulation profile is used during the DCE Cycle. Default is 1.6 s (01b). Bit 3 - RESERVED - This bit will default to ‘0’. Changing this bit will have no effect. Bit 2 - RESERVED - This bit will default to ‘0’. Changing this bit will have no effect. Bit 1 - RESERVED - Do not change. This bit will read ‘0’ and should not be written to a logic ‘1’. Bit 0 - RESERVED - Do not change. This bit will read ‘0’ and should not be written to a logic ‘1’.
