Abstract
An interrupt signal generating device comprises interrupt detection units ( ) each adapted to output a detection signal (DET- to DET-n) in response to a respective input signal (IN- to IN-n) representing an interrupt event; and an interrupt handler unit ( ). The interrupt handler has a plurality of input terminals for receiving the detection signals (DET- to DET-n) and a plurality of output terminals for outputting corresponding interrupt signals to a CPU, and signal distribution means ( ) connecting said input terminals to said output terminals and establishing a predetermined but changeable assignment between the input and output terminals, wherein each of said input terminals is assigned to one of said outputs terminals such that an interrupt signal (INT- to INT-n) is output from this output terminal in response to a detection signal (DET- to DET-n) applied to the respective input terminal.
