Abstract: When initializing a card-shaped device inserted in a card interface, operation mode acquiring means incorporated in an electronic device acquires operation mode information, stored in a register file incorporated in the card-shaped device, by a predetermined procedure using a predetermined pin. Operation mode setting means incorporated in the electronic device executes signal assignment on a plurality of data pins peculiar to an operation mode indicated by the acquired operation mode information, thereby switching a data transfer width, and allowing the card-shaped device to operate in the operation mode.

Abstract: An interrupt control apparatus of a microprocessor comprises a controller for selecting an interrupt requirement having a highest priority from a plurality of interrupt requirements and outputting the signals indicative of this highest priority; a comparator for comparing the priority of the interrupt requirement selected by the interrupt controller with mask information indicating a priority as to whether the interrupt requirement is executed or not; a detector for detecting whether the priority of the interrupt requirement is outputted from the controller or not; and a judging device for stopping an output of the controller when the priority of the selected interrupt requirement is lower than the priority of the mask information.

Abstract: A microinstruction executing system includes a sequencer for controlling sequential readout of microinstructions from a ROM for storage in a microinstruction register and for subsequent decoding by a decoder. In response to a destination control signal (source side) from the decoder, a general register will transfer data to a destination bus and in response to a destination control signal (destination side) from the decoder, data from the destination bus will be transferred to one of a destination data register or a source data register. In response to a source control signal (source side) from the decoder, the general register will transfer data to a source bus and in response to a source control signal (destination side) from the decoder data from the source bus will be transferred to one of the destination data register or source data register.
