Abstract
PURPOSE: To secure software processing time sufficiently without being troubled by a display, by constituting so that the data transfer for display is disregarded, on a software.
CONSTITUTION: The RAM17 is able to not only read or write through the base line 25 the contents of the cell whose address is designated by the contents of the Y- register 15 and the X-register 16, but also directly read them out to the store circuit 18 for display without making them pass through the bas line. At this time, the X- address which is designated by a signal 23 required once when necessary is separated from the X-data by the signal 25 and selected. In this case, 1 bit disignated by the address of the RAM corresponds to 1 segment of display by 1:1. Accordingly, in case of the processing of the software, it is completed to rewrite a data by only rewriting a data of the bit of the RAM corresponding to a necessary segment. As a result, it can be disregarded to transfer a display data on the software.
