Problems solved by technology

In this adapter device, it is also necessary to perform switching such as stopping parallel transfer and serial transfer for an electronic device that performs input and output of the above-mentioned information data in a parallel transfer method, but it is not easy to identify such an electronic device and perform switching. , so traditionally this identification and switching is not implemented
[0006] In view of this point, this application intends to solve the problem that in traditional devices, it is not easy to carry out identification of electronic devices and switching of internal circuits, etc., in traditional electronic devices, information processing devices, adapter devices and information exchange systems In, this identification and switching is not implemented

Embodiment Construction

[0107] In the present invention, while the information data input and output mechanism based on parallel transfer is additionally set, a register having a predetermined writing area and a reading area is set to perform setting when implementing the function, and a predetermined address of the register is set to indicate additional The prescribed code for the input and output functions based on the information data transferred in parallel is provided, so that the electronic device can be identified by simple means, and the operation such as switching of the internal circuit can be performed very smoothly by using it.

[0108] Hereinafter, in describing the present invention with reference to the accompanying drawings, FIG. 1 is a block diagram showing the configuration of an embodiment of an electronic device and an information processing device to which the present invention is applied.

[0109]In FIG. 1 , the left side of the drawing shows the configuration of main components ...

Abstract

A memory card (200) has a parallel interface (22) in addition to a serial interface (21). A register (24) has flags indicating 'presence / absence of the parallel interface (22)', 'presence / absence of the address conversion function', 'presence / absence of memory' and 'which of the serial interface (21) and the parallel interface (22) is to be used'. By rewriting the flag 'which of the serial interface (21) and the parallel interface (22) is to be used', it is possible to switch the interface.

Description

technical field [0001] The present invention relates to an electronic device that implements any function, such as an information processing device that is freely detachable, an information processing device using the electronic device, an adapter device that mediates information exchange between them as necessary, or an electronic device using The information exchanging system of these devices particularly relates to an electronic device which has the same shape as a memory card device or a semiconductor memory device similar thereto, is connected to a connection portion of these devices, and performs a memory function or any other function, or is connected to the electronic device Related information processing device, adapter device and information exchange system. Background technique [0002] Having the same shape as a memory card device detachably installed in an information processing device, or a semiconductor memory device similar to it, connected to a connection po...
