In an digital video disk player the timely acquisition of specific data types is particularly important during trick mode operation. During trick modes a controller can provide enhanced control capability by employing interrupt requests having priorities that differ from those used during normal play mode operation. A method for controlling a microcontroller in digital disk apparatus having at least two reproducing modes. The method comprises the steps of prioritizing the microcontroller interrupts during a first reproducing mode, and in a second reproducing mode reordering the microcontroller interrupt priorities.

Once accepting an interrupt, the control is such as to not accept any interrupt including that highest priority within the group to which the interrupt about to be processed belongs by referring to the interrupt management table. Then the vector number for the highest priority in the group from among the received interrupts is selected. Then the processing of a handler for the selected vector number is executed. The priority of the executed interrupt processing is reset to the lowest priority in the group.
