A data processing system nested interrupt controller 24 responsive to priority level values 28, 30 associated with respective interrupt handling programs to control the execution of those interrupt handling programs. The priority level values have a first portion 28 which controls whether or not a pending interrupt handling program will pre-empt an already active interrupt handling program and a second portion 30 which controls which of a plurality of pending interrupt handling programs will be executed next when they share the same value for the first portion of their priority level value.
