9 / 35 page ADM1033 http://onsemi.com 9 The ADM1033 responds to the following commands: Prepare to ARP (General) Reset Device (General and Directed) Get UDID (General and Directed) Assign Address (General) Table 5. INTERNAL REGISTER DESCRIPTIONS Register Description Configuration Provides control and configuration of various functions on the device. Conversion Rate Determines the number of measurements per second completed by the ADM1033. Address Pointer Contains the address that selects one of the other internal registers. When writing to the ADM1033, the first byte of data is always a register address, written to the address pointer register. Status Provides the status of each limit comparison. Interrupt Mask Allows the option to mask ALERTs due to particular out-of-limit conditions. Value and Limit Stores the results of temperature and fan speed measurements, along with their limit values. Offset Allows the local and remote temperature channel readings to be offset by a twos complement value written to them. These values are automatically added to the temperature values (or subtracted from them if negative). This allows the systems designer to optimize the system if required, by adding or subtracting up to 15.875C from a temperature reading. THERM Limit and Hysteresis Contains the temperature value at which THERM is asserted and indicates the level of hysteresis. Look-up Table Used to program the look-up table for the fan speed-to-temperature profile. THERM % On-time and THERM % Limit Reflects the state of the THERM input and monitors the duration of the assertion time of the signal as a percentage of a time window. The user can program the length of the time window. Table 6.

ARP denotes ARP-capable mode, FD denotes fixed and discoverable mode. Table 7. UDID VALUES Bit No. Name Function Value <127:120> Device Capabilities Describes the ADM1033’s capabilities (for instance, that it supports PEC and uses a random number address device). 11000001 <119:112> Version/Revision UDID version number (Version 1) and silicon revision identification 00001010 <111:96> Vendor ID Analog Devices vendor ID number, as assigned by the SBS Implementer’s Forum or the PCI SIG. 00010001 11010100 <95:80> Device ID Device ID. 00010000 00110100 <79:64> Interface Identifies the protocol layer interfaces supported by the ADM1033. This represents SMBus 2.0 as the Interface version.. 00000000 00000100 <63:48> Subsystem Vendor ID Subsystem Vendor ID = 0 (subsystem fields are unsupported). 00000000 00000000 <47:32> Subsystem Device ID Subsystem Device ID = 0 (subsystem fields are unsupported). 00000000 00000000 <31:0> Vendor Specific ID A unique number per device.
