Abstract
In accordance with an embodiment, an integrated circuit comprises a plurality of general-purpose terminals, a first register, a second register and an assignment section. The first register stores a value indicating a state of the general-purpose terminal. The second register stores a value of a register indicated by an address based on the assigned address. The assignment section configured to assign addresses of at least a part of the first registers among the first registers as addresses to be stored in the second register adjacently to a predetermined address in the second register and addresses subsequent to the predetermined address based on connection with the general-purpose terminal.
Claims20
An integrated circuit, comprising:
- a plurality of general-purpose terminals;
- a first register configured to store a plurality of values each indicating a state of each corresponding general-purpose terminal;
- a second register configured to store a value of a register indicated by an address based on an assigned address;
- and
- an assignment section configured to assign addresses in at least apart of the first register as addresses to be stored in the second register adjacent to a predetermined address in the second register and addresses subsequent to the predetermined address based on connection with any of the general-purpose terminals.
An image forming apparatus, comprising:
- a plurality of general-purpose terminals;
- a first register configured to store a plurality of values each indicating a state of each corresponding general-purpose terminal;
- a second register configured to store a value of a register indicated by an address based on an assigned address;
- and
- an assignment section configured to assign addresses of at least apart of the first register as addresses to be stored in the second register adjacent to a predetermined address in the second register and addresses subsequent to the predetermined address based on connection with any of the general-purpose terminals, wherein
- at least one of an external device for executing an image forming processing of forming an image on an image receiving medium, an external device for executing an image reading processing of reading an object, and an external device for executing a post-processing on the image receiving medium on which the image is formed is connected to the general-purpose terminals.
An address assignment method by an integrated circuit comprising a general-purpose terminal, a first register for storing a value indicating a state of the general-purpose terminal, and a second register for storing a value of a register indicated by an address based on the assigned address, comprising:
- assigning addresses of at least a part of the first register as addresses to be stored in the second register adjacent to a predetermined address in the second register and addresses subsequent to the predetermined address based on connection with the general-purpose terminal.
