Abstract

PURPOSE:To process each type of program without impairing the memory information at the initial starting time of a channel device, by providing a channel control register within a channel and clearing the related hardware without proceeding to a self-diagnosis. CONSTITUTION:The initial program is started through a CPU1, and an initializing process is given to the information stored in a RAM13 within a channel 3 by said initial program. The channel 3 has a channel control register CCR21 as well as a function that waits for an indication of the CPU1 without proceeding to a self-diagnosis just by supplying a clear signal to the hardware relating to the channel 3 and by a command indicating a channel clear and given from the CPU1. The CPU1 gives a command of channel clear to the channel 3 and then gives an indication through the CCR21. Then an MPU11 of the channel 3 decodes the indication to clear the related hardware and at the same time starts an individual program of a ROM12 with a command given from the CPU1. Thus a process is carried out through the MPU11.
