ABSTRACT:
A control system for a serial data channel for a disk file is disclosed in which a microcontroller is used as the control means. The microcontroller has an input port and an output port, while the serial data channel has a data register. The connections of the data register to the input and output port and the parallel by bit input and output busses on which write data and read data is sent provides a plurality of different data transfer loops through the data register which can be selected under the control of the microcontroller. The arrangement permits functions to be achieved by the microcontroller that heretofore were performed by another device connected to the controller or by special hardware.
