Summary of Supported Commands and Feature Differences Between the LTM4676A and the LTM4676 (Items of Greatest Significance Indicated by Gray-Shaded Cells; Common Commands, Values and Attributes Indicated by Non-Shaded, Merged Cells) PMBus COMMAND NAME, OR FEATURE CMD CODE (REGISTER) COMMAND OR FEATURE DESCRIPTION LTM4676A NVM FACTORY-DEFAULT VALUE AND/OR ATTRIBUTES LTM4676 NVM FACTORY-DEFAULT VALUE AND/OR ATTRIBUTES PAGE PAGE 0x00 Channel or page currently targeted for paged communications. No difference: 0x00, read/write, non-paged, not stored in NVM. 86 OPERATIONn 0x01 Operating mode control. On/off, margin high and margin low. No difference: 0x80, read/write, paged, stored in user-editable NVM. 90 ON_OFF_CONFIGn 0x02 RUNn pin and On/Off Configuration. No difference: 0x1F, read/write, paged, stored in user-editable NVM. 89 CLEAR_FAULTS 0x03 Clear any fault bits that have been set. No difference: default value not applicable, send byte only, non-paged, not stored in NVM. 114 PAGE_PLUS_WRITE 0x05 Write a command directly to a specified page. Default value not applicable, write- only, non-paged, not stored in NVM. Command not supported. 86 PAGE_PLUS_READ 0x06 Read a command directly from a specified page. Default value not applicable, read/ write, non-paged, not stored in NVM. Command not supported. 87 WRITE_PROTECT 0x10 Level of protection provided by the device against accidental changes. No difference: 0x00, read/write, non-paged, stored in user-editable NVM. 87 STORE_USER_ALL 0x15 Store user operating memory to EEPROM (user-editable NVM). No difference: default value not applicable, send byte only, non-paged, not stored in NVM. 125 RESTORE_USER_ ALL 0x16 Restore user operating memory from EEPROM. Default value not applicable, send byte only, non-paged, not stored in NVM. Identical to MFR_RESET command (0xFD). Reserved. Execute MFR_RESET command (0xFD), instead. 126 CAPABILITY 0x19 Summary of PMBus optional communication protocols supported by this device. No difference: 0xB0, read-only, non-paged, not stored in NVM. 113 PMBUS COMMANDS Table 1 lists supported PMBus commands and manufacturerspecificcommands.Acompletedescription of these commands can be found in the “PMBus Power System Management Protocol Specification – Part II – Revision 1.2." Users are encouraged to reference this specification. Exceptions or manufacturer specific implementations are listed in Table 1. All commands from 0xD0 through 0xFF not listed in this table are implicitly reserved by the manufacturer. Users should avoid blind writes within this range of commands to avoid undesired operation of the part. All commands from0x00through0xCFnotlistedinthistableareimplicitly not supported by the manufacturer. Attempting to access non-supported or reserved commands may result in a CML command fault event. All output voltage settings and measurements are based on the VOUT_MODE setting of 0x14. This translates to an exponent of 2–12. IfPMBuscommandsarereceivedfasterthantheyarebeing processed, the part may become too busy to handle new commands. In these circumstances the part follows the protocols defined in the PMBus Specification v1.2, Part II, Section 10.8.7, to communicate that it is busy. The part includes handshaking features to eliminate busy errors and simplify error handling software while ensuring robust communication and system behavior.
