Abstract: The present solution targets independent or inter-dependent resource management scenarios such as multi-sensor and other scenarios of possible process/component sharing, intended for individual or group synchronized core task management as part of a flexible long-term solution for monitoring, self-calibration, built-in self-testing, measurements and/or group synchronization dependant strategies. An extension to I2C compatible instruments is described. Disclosed is a module comprising an interpreter sub-module, for receiving and responding to I2C sequences and a register bank module comprising a plurality of registers for storing values. The disclosed module and method of operation can be used for initialization, measurement, and resource management through mixed-signal analog bus scheduling, synchronization and group addressing for built-in calibration strategies for example.
