Abstract
A data processing system having a plurality of interrupt sources coupled to provide interrupt handling of a process currently executing at a specified interrupt level. A level change signal which may be generated by the process itself may change the specified level of such process to another level which may make such process less interruptable to other interrupt sources. The level change provided takes place without interrupting the execution of such process.
