Abstract

An input/output control device includes: a bus connected to an input interface; a plurality of circuit selectors which are connected to the bus and to which validity or invalidity of an operation is set, each circuit selector outputting a signal of the bus when the validity is set; a plurality of logical circuits which are respectively provided to each of the circuit selectors, each logical circuit performing a logical operation when a signal is inputted from the circuit selector; an output selector which is connected to the bus and to which validity or invalidity of an operation is set, the output selector outputting a signal of the bus to an output interface when the validity is set; and an operation part which validates or invalidates the plurality of circuit selectors or the output selector based on an operation order of the plurality of circuit selectors and the output selector.

An input/output control device comprising:

a bus which is connected to an input interface to which a signal is inputted from outside;
a plurality of circuit selectors which are connected to the bus and to which validity or invalidity of an operation is set, each circuit selector outputting a signal of the bus when the validity is set but not outputting the signal of the bus when the invalidity is set;
a plurality of logical circuits which are respectively provided to each of the circuit selectors, each logical circuit performing a logical operation when a signal is inputted from the circuit selector and outputting a signal representing an operation result to the bus;
an output selector which is connected to the bus and to which validity or invalidity of an operation is set, the output selector outputting a signal of the bus to an output interface when the validity is set but not outputting the signal of the bus to the output interface when the invalidity is set;
and
an operation part which validates or invalidates the plurality of circuit selectors or the output selector based on an operation order of the plurality of circuit selectors and the output selector.
