Abstract
Aspects of a method and system for detecting interrupts from detachable electronic accessories or peripherals are provided. In this regard, a hardware audio CODEC may be operable to compare a voltage on one or more biased pins of an accessory or peripheral port to one or more reference voltages and filter one or more output signals generated from the comparison. When an accessory or peripheral is coupled to the accessory or peripheral port, interrupts from the accessory or peripheral may be detected based on results of the comparison and/or the filtering. An interrupt may be detected when the voltage on the one or more pins may be below the one or more reference voltages. An interrupt may be detected when the voltage on the one or more pins may be below the one or more reference voltages for a plurality of consecutive clock cycles.
