PURPOSE:To alter optional set data in a program step easily, by switching the data for setting applied to a port for inputting selectively by the content of a register and storing in a memory device. CONSTITUTION:Set data stored preliminarily in a memory device 3 is outputted from ports 2a-2g of a port 2 for outputting by reading the set data corresponding to the ports 2a-2h of the port 2 for output of a program step stored in the device 3. Further, the set data corresponding to the port 2h outputted from the device 3 is not outputted to the port 2h and said data are set by the set data given to a port 1h by a set part of a programable oscilloscope corresponding to the port 2h. On one hand, when a write signal WE is given to the port 1h, the set data is written in the device 3. In this manner, the optional set data in the program step is altered easily. |
