Abstract
In a memory within a micro controller, a method for addressing a page for inputting and outputting the page data on a bus. The method includes steps of producing a first control signal activated at a data update mode in which a read or write operation is executed, and determining in response to the first control signal whether the read or write operation is executed for the same page or a different page.
Claims9
In a memory within a micro controller which includes a first area in which only direct addressing is available, a second area in which only indirect addressing is available and a third area in which both direct and indirect addressing are available, the third area having a plurality of pages, a method for addressing a page for inputting and outputting page data on a bus comprising steps of:
- producing a first control signal activated at a data update mode in which a read or write operation is executed;
- and
- determining in response to the first control signal whether the read or write operation is executed for a same page or a different page.
In a memory within a micro controller which includes a first area in which only direct addressing is available, a second area in which only indirect addressing is available and a third area in which both direct and indirect addressing are available, the third area having a plurality of pages, a device for addressing a page for inputting and outputting the page data on a bus, comprising:
- a control signal generating means for generating a first control signal activated when a page having a specific region is accessed and a second control signal activated when a data update mode is executed to update a region;
- a page selection means coupled to the bus, for selecting the page having the specific region enabled by the first control signal;
- and
- a multiplexing means using address signals of the page, which is read out by the second control signal, as address signals of the page to be written.
