PURPOSE:To achieve lower power consumption and enhance the flexibility of the PLA system by providing a plurality of control instructions discriminated by the state information of watch or display operation and key input information to the same read-out step. CONSTITUTION:The instruction assigning the next page of ROM 1 is being inputted to the column part (a) of the ROM 1, a processing instruction is inputted to the column portion (b) and address data are inputted to the column portion C. This system subsequently reads out the control insttuctions having been written in this way according to the specified timing pulses and has information processing for the purpose of watch operation and display operation done based on these, wherein a plurality of the control instructions discriminated by the state operation of the watch or display operation and key input information are provided within the same timing period, whereby rational information processing is made possible and in addition, the change and addition of the functions also become possible through changing of the ROM 1, ROM 13. |
