Abstract

PURPOSE: To make arrangement so that the interruption can be received within a given period of time without fail, by sending out the interruption signal at all times in case the interruption signal which has finished waiting its rotation is not received more than fixed times.
CONSTITUTION: The sector address which is instructed by the reading command SET. SEC from the upper device is maintained in the register 6, and as for the address on the disk 1, the sector address is counted with the counter 5. When the contents of the register 6 and the counter 5 conform each other, the interruption signalI which has finished waiting its rotation is issued. The signal I is counted by the counter 9, and when it reaches the number of times which is fixed, the interruption signal I is always sent out through FF12. In case of the aforesaid method, since the interruption can be received without fail within a given period of time, errors such as time-over, etc. can be prevented.
