68 / 116 page  Programmable USB Port Power Controller with Charger Emulation Datasheet Revision 1.4 (07-16-13) 68 SMSC UCS1002 DATASHEET Chapter 10 Register Description The registers shown in Table 10.1 are accessible through the SMBus or I2C. An entry of ‘-’ indicates that the bit is not used. Writing to these bits will have no effect and reading these bits will return ‘0’. An entry of RES indicates that the bit is reserved. Writing to a RES bit may cause unexpected results and reading from a RES bit will return either ‘1’ or ‘0’ as indicated in the bit description. While in the Sleep state, the UCS1002 will retain configuration and charge rationing data as indicated in the text. If a register does not indicate that data will be retained in the Sleep power state, this information will be lost when the UCS1002 enters the Sleep power state.
