Abstract
The control system controls the operation of a charge coupled device. The operation of the charge coupled device is responsive to a shift clock signal of a given frequency and a shift enable signal. The control system includes a timer for generating one of a number of shift clock signals. Each of the shift clock signals has a different frequency. A programmable register stores a plurality of control bits which may be programmed into the program memory of the control system. A multiplex switching is used for selecting one of the shift clock signals in response to the state of the control bits and directing the selected shift clock signal to the charge coupled device. An address decoder in response to addressing by the microprocessor, generates the shift enable signal which signal is directed to the charge coupled device concurrently with the presence of the selected shift clock signal.
