PROBLEM TO BE SOLVED: To realize the variable display control and game control of a higher level by providing an information selection means for selecting information not detecting the generation of an error by a transmission error detection means as valid information in an information transmission means. SOLUTION: At the time of checking a check sum, all the data of com0-com7 stored in a preliminary storage area are added and the low-order 7 bits are obtained. The obtained low-order 7 bits are compared with contents stored in a storage area prepared corresponding to comC. When they are matched with each other, the data of com0-com7 are stored in a microcomputer command data storage area for LCD control. Besides, when they are not matched with each other, since the data stored in the preliminary storage area are not processed at all and cleared at the time of inputting the next comH, the data are abandoned as a result. Thus, data are transferred from a microcomputer for the game control to the microcomputer for the LCD control. |
