DS20005346B-page 61 UCS1003-1/2/3 10.0 UCS1003-1 REGISTER DESCRIPTION The registers shown in Table 10-1 are accessible through the SMBus or I2C protocol. While in the Sleep state, the UCS1003-1 will retain configuration and charge rationing data as indicated in the text. If a regis- ter does not indicate that data will be retained in the Sleep power state, this information will be lost when the UCS1003-1 enters the Sleep power state. TABLE 10-1: REGISTER SET IN HEXADECIMAL ORDER Register Address Register Name R/W Function Default Value Page No. 00h Current Measurement R Stores the current measurement 00h 62 01h Total Accumulated Charge High Byte R Stores the total accumulated charge delivered high byte 00h 63 02h Total Accumulated Charge Middle High Byte R Stores the total accumulated charge delivered middle high byte 00h 63 03h Total Accumulated Charge Middle Low Byte R Stores the total accumulated charge delivered middle low byte 00h 63 04h Total Accumulated Charge Low Byte R Stores the total accumulated charge delivered low byte 00h 63 0Fh Other Status R Indicates emulation status as well as the ALERT# and A_DET# pin status 00h 64 10h Interrupt Status See Register 10-3 Indicates why ALERT# pin is asserted 00h 65 11h General Status R/R-C Indicates general status 00h 67 12h Profile Status 1 R Indicates which charger emulation profile was accepted 00h 68 13h Profile Status 2 R 00h 70 14h Pin Status R Indicates the pin states of the internal control pins 00h 72 15h General Configuration R/W Controls basic functionality 01h 67 16h Emulation Configuration R/W Controls emulation functionality 8Ch 74 17h Switch Configuration R/W Controls advanced switch functions 04h 76 18h Attach Detect Configuration R/W Controls Attach Detect functionality 46h 77 19h Current Limit R/W Controls the maximum current limit 00h 79 1Ah Charge Rationing Threshold High Byte R/W Controls the current threshold, ITHRESH, used by the charge rationing circuitry FFh 80 1Bh Charge Rationing Threshold Low Byte R/W Controls the current threshold, ITHRESH, used by the charge rationing circuitry FFh 80 1Ch Auto-Recovery Configuration R/W Controls the auto-recovery functionality 2Ah 81 1Eh IBUS_CHG Configuration R/W Stores the limit for IBUS_CHG used to determine if emulation is successful 04h 82 1Fh tDET_CHARGE Configuration R/W Stores bits that define the tDET_CHARGE time 03h 83 20h BCS Emulation Enable R/W Enables BCS charger emulation profiles 06h 84 21h Legacy Emulation Enable R/W Enables Legacy charger emulation profiles 00h 85 22h BCS Emulation Time-out Configuration R/W Controls time-out for each BCS charger emulation profile 10h 86 |
