Abstract

Technologies are described herein for ensuring remediation of hung multiplexer bus channels between a baseboard management controller (BMC), multiplexer, and IC device such as a sensor. In particular, a BMC, which is in operative communication with one or more sensors via a multiplexer, comprises an IC interface and general purpose input/output (GPIO) interface. Upon transmitting an IC command to the IC device via the multiplexer and subsequently transmitting a stop sequence to the IC device via the multiplexer, the BMC then immediately transmits a reset signal to the multiplexer's reset input. When the multiplexer receives the reset signal, it resets all registers and deselects all channels, thereby remediating any hung channels and ensuring the next communication from the BMC is successful.
