Method of process control for data processing system peripheral device priority circuit

摘要

The method involves the temporary storage of time and date data in a receiver and decoder unit until the complete timing signals have been received before being transferred to the data processing system. As long as the time or date data have not been completely received, an actual time duration is continuously maintained and compared with a predefined maximum time value. If the maximum time is exceeded, data transfer from a data entry unit to the data processing system is interrupted and the receiver and decoder unit re-initialized.
