Abstract
Embodiments of the present invention provide a method and apparatus to allow an I/O controller to alert an external controller using an enhanced SMBus implementation that enables bi-directional capability on SMBALERT#. I/O controller includes an auxiliary control register and alert output enable (AOEN) register. When host sets AOE bit in auxiliary control register, SMBALERT# signal is configured as an output signal with bi-directional functionality. External controller uses an interface command to write to AOEN register and determine events/conditions it wants to be alerted on. SMBALERT# is activated in response to a detected event/condition. In response to SMBALERT#, external controller determines the alert generation condition using byte read commands on the system management bus, and clears SMBALERT#.
