Abstract

PURPOSE: To make it possible to diagnose possessory functions efficiently without connecting any I/O by providing a microcomputer and selector bus control circuit and also by using a control signal and data sent out relatively.
CONSTITUTION: Selector channel 20 is provided with microcomputer μCPU29, selector bus control circuit 31, simulator 43 (making function diagnoses and simulation), etc. Then, μCPU transmits and receives data to and from each register through internal bus 28 and also transmits and receives data to and from I/O by way of input-output bus 34, selector bus driven-receiver circuit 35 and selector bus 36. Further, μCPU29 is previously connected to circuit 31 by way of start signal line 30 to which the transfer start command signal is sent and end signal line 32 through which the transfer end interruption signal passes. Then, each status request signal, data available signal and data request signal supplied from μCPU29 or circuit 31 are sent to bus 36 through corresponding OR circuits respectively and then diagnosed 43.
