ABSTRACT:
A microprocessor controlled circuit and associated firmware program provide a capability to change output frequencies when required. A plurality of frequency generating devices are included, and logic circuitry is used to determine which frequency generator is coupled to the microprocessor to provide the desired output frequency. The logic circuitry is controlled by the microprocessor in accordance with a comparison of a data pattern stored in the internal random access memory of the microprocessor with at least one of a plurality of data patterns stored in a read only memory, which data patterns represent the frequency generating devices.
