Abstract

PURPOSE: To initialize a unit with restraining the damage caused by hang-up to a minimum, by making the unit into modules by function units and by detecting the hang-up state and by making it possible to initialize the unit for every module.
CONSTITUTION: Though processor unit PU101 executes micro program FW stored in ROM103, other modules are hard-cleared simultaneously in the initialization routine of FW by writing all 1 to register REG110 for reset control, which is provided in device control unit DCU106, and writing all 0 to it next. Next, adapter FDC107 is instructed to read and load the part of FW, which is not stored in ROM103, from disc unit FDD to RAM104, and preset required for respective registers in each adapter is performed. After the initialization completion, the busy state of adapters such as FDC107 is monitored. The busy counter of PU101 is counted up from the busy state; and in case of overflow, the initializing signal is issused for the part causing over-flow.
