Title: Data processing
IPC: G06F11/07
Filed: 1978-05-19
Abstract: For this purpose, an error registered in an error register (E-REG) is examined in an analysis network (ANW) and the latter generates a start signal (STE) for a pause generator (PG), the output signals of which stop the system clock generator (TG) of the data processing system at a defined point before a particular system clock pulse (T1) and asynchronously start it again. With the start at a particular system clock pulse, an error routine can be started in a defined manner without there being a possibility of sequence errors. The circuit arrangement is used as pause generator (PG) for stopping the system clock generator (TG) in a defined manner before an error routine and can be used in error routines controlled by hardware or by microprogram. <IMAGE>
