Abstract
The digital interface unit (1) for control of a peripheral device, especially for controlling a magnetic valve for an injection device, includes a plurality of output registers (2 to 5), which store and output a set of control variables applied to the input sides of the respective output registers in response to a control signal (18, MST E). So that the control variables are output from the output registers exactly simultaneously even though they are received sequentially, at least one group of buffer registers (12 to 15, 24 to 27) is connected to the output registers (2 to 5). The buffer register or registers provides intermediate storage for the control variables prior to output from the interface unit.
