Abstract: The invention provides an interrupt handling system to process a generated interrupt. At least one input is arranged to provide a predetermined active level, with a detection circuit associated with the input which is selectively configurable to detect either the active level or an inactive level. An interrupt request message causes the detection circuit to be configured to detect the active level, so that an enable logic is caused to generate an interrupt.
The invention provides an integrated circuit and a method of generating interrupts using the above system, and a consumer electronic device in the form of a set top box or DVD Read and/or Write device.
