PURPOSE:To cope softly with the general-purpose property of a monitor device and a change of the constitution of a system by converting an interface to a standard interface of the inside of the monitor device, and thereafter, sending and receiving data to and from a memory. CONSTITUTION:In case when data is outputted to object devices 2-4, the contents of the first memory area 11 are stored in a register 25, and subsequently, a value of an address pointer 22 is used as a memory access address by a selector 24, and data read out of the second memory area 12 is stored in a register 26. Thereafter, it is requested to receive the data, to the device designated by a device address which has been set to the register 25 through an interface converting part 31. In case when a data is inputted, an output of the data is requested to the object device designated by the device address, and when the data is received, it is stored in the register 26, and thereafter, written in the second memory area 12 indicated by the address pointer 22. |
