ABSTRACT:
A data processor includes an interrupt control unit (102); a direct memory access control unit (103); a selection unit (104) for selecting a connection of ready and error signals from a serial communication control unit and external interrupt and DMA request signals with interrupt inputs to the interrupt and the DMA control units; and a selection setting unit (105) for setting a selection mode of the selection unit, thereby making possible to not only switch between a process by interrupt and a process by DMA transfer by programming according to the application but also make efficient use of the hardware resources in the data processor.
