ABSTRACT:
The present invention relates to a data processing device that can perform independently a debug interruption process and a program interruption process. The data processing device consists of first and second interruption selection code producing units for producing interruption selection codes according to the first and second interruption requests respectively; and a switching unit for selectively switching to either one of interruption selection codes from said first and second interruption selection code producing units. When the second interruption request is received, the switching unit selects preferentially and output an interruption selection code from the second interruption selection code producing unit, thus jumping to an interruption process program according to the interruption selection code so that an interruption process according to said second interruption request is performed. The data processing device is applicable to RISC-type central processing units in computing systems.
