<p>PURPOSE:To secure high accuracy by providing a data generating means which generate data with a specific period according to a reference clock outputted by a reference oscillator and a microcomputer for system control. CONSTITUTION:A data generating circuit 13 is connected to a communication interface circuit 14 to control a part 3 to be controlled and display data showing the operation state of the part 3 to be controlled is sent to a line 4 through the communication interface circuit 14. Then the communication interface circuit 21 of a CPU 2 for a timer receives display data from a CPU 1 for system control and sends it to the CPU 1 for system control. The received display data 21a is processed by a data generating circuit 22 and supplied to a display circuit 5. In this case, the transmission period T of the display data 21a is determined with the high-accuracy clock from a reference generator 12, so the period is extremely accurate.</p> |
