A switched mode power supply comprises a communication interface including an address terminal configured to couple to an external resistor for setting a communication address of the switched mode power supply. A control circuit is configured to determine the value of the external resistor a first time with a first technique and set the communication address of the switched mode power supply based on the value of the external resistor determined using the first technique if the value of the external resistor is greater than the threshold value. The control circuit is also configured to, if the value of the external resistor is less than the threshold value, determine the value of the external resistor a second time with a second technique and set the communication address of the switched mode power supply based on the value of the external resistor determined using the second technique.

In one embodiment, a device is disclosed comprising a data storage device; and an address resolution protocol (ARP) state machine communicatively coupled to the data storage device and included within a power management integrated circuit (PMIC), the ARP state machine configured to assign an address to the data storage device and validate requests for data stored in the data storage device received over a bus.

An information handling system includes an identification resistor, calibration circuitry, and a system-on-a-chip (SOC). The SOC sets the calibration line to a first digital state to place the calibration circuitry in an inventory mode. While the calibration circuitry is in the inventory mode, the SOC determines an inventory amount of time to charge the capacitor to a voltage substantially equal to a threshold voltage. The SOC then sets the calibration line to a second digital state to place the calibration circuitry in a calibration mode. While the calibration circuitry is in the calibration mode, the SOC determines a calibration amount of time to charge the capacitor to the voltage substantially equal to the threshold voltage. The SOC determines a resistance of the identification resistor based on the inventory amount of time and the calibration amount of time. The SOC also determines bit strapping information corresponding to the determined resistance.

The device ID setting method comprises; (a) recording connections between pins between the first electronic device and the second electronic device by the second electronic device; (b) applying the connections as a device ID of the first electronic device by the second electronic device; and (c) setting pins of the first electronic device such that the data pins of the second electronic device are coupled to the data pins of the first electronic device.

A multi-channel, selectable identity tagging (MCSIT) data translator includes a word monitor port and a channel identifier (ID) tagger. The word monitor port is configured to receive a word generated by a specified one of a plurality of controllable components.

The word monitor port is also configured to generate a channel ID corresponding to the specified controllable component and a word type corresponding to the word. The channel ID tagger is configured to determine whether to tag the word with the channel ID based on the word type and, based on the determination, to generate a processed word.

A method for electronic device identifier assignment at a host computing device includes receiving, from a separate electronic device, a current local identifier of the separate electronic device and a full unique identifier of the separate electronic device. A host-specific identifier is assigned to the separate electronic device by, based at least in part on determining that the current local identifier of the separate electronic device is included in a set of local identifier values available for assignment, assigning the host-specific identifier to the separate electronic device with a same local identifier value as the current local identifier. Based at least in part on determining that the current local identifier of the separate electronic device is already assigned by the host computing device to a different separate electronic device, the host-specific local identifier is selected from the set of local identifier values available for assignment and assigned to the separate electronic device.
