21 / 39 page  4+1 Phase Dual Output Control IC IR3531 March 22, 2012 | FINAL | V2.27 21 When the processor (master) issues a Get command, it transmits the intended controller address and the address of the register it wants to read. The addressed controller acknowledges the command and returns the requested data. Similarly, when the processor issues a Set command, it transmits the intended controller address and the data it wants to insert. The only exception is the SetRegADR command which is used to declare the register address that SetRegDAT will alter. The controller acknowledges these commands. Parity checking is not enforced on SetRegADR/SetRegDAT. TABLE 2: SUPPORTED COMMAND Command Description SetVIDfast Slews VOUT to a new Programmed setpoint at 20mV/usec SetVIDslow Slews VOUT to a new Programmed setpoint at 5mV/usec SetPS Sets power state SetRegADR Declares the address of the register to be written to SetRegDAT Writes data to the SetRegADR declared register GetReg Read data of a specified register TestMode Test mode is used for final test trimming of the IR3531 and is not available to users. Note: SetVID decay is not supported TABLE 3: SUPPORTED REGISTER Register Description VendorID Identifies the VR vendor ProductID Identifies the product model ProductRev Identifies the product revision SVID Protocol ID Identifies the version of SVID protocol VR Capability Communicates functions the IR3531 supports Status1 Reg Stores VR status data Status2 Reg Stores SVID bus errors Temp Zone Temperature zone from Rail0 sensor Output Current Stores output current for Rail0/Rail1 Status2_last_read Stores previous data of status 2 ICC Max Programs the maximum supported output current Temp Max Programs maximum operating temperature SR-fast Stores the fast slew rate value SR-slow Stores the slow slew rate value Vboot Overrides the default Vboot value Vout Max Programs the maximum supported operational Vout VID Setting Register contains the current VID setting Power State Register contains the current power state VID Offset 1 Allows margining around the VID setpoint Multi VR Config Configures other VR-s on the same SVID bus SetRegADR Scratch pad register for temporary storage of the SetRegADR pointer register Note 1: VID Offset commands that attempt to push the VID above 1.52V or below 0V are not acknowledged. |
