ABSTRACT:
Apparatus for transferring control of digital command execution from dedicated digital logic to an off chip microprocessor. A command register receives said digital commands. A decoder connected to the command register will be connected via a decoded command to a filter where it may be passed to a dedicated execution logic circuit for execution, or blocked from execution, depending on a preset block code in the filter. Blocked commands are identified by an interrupt to the microprocessor, permitting the microprocessor to execute the command.
