ABSTRACT:
A data processing device includes a circuit having status conditions wherein a particular set of the status conditions can occur in operation of the circuit. An instruction register operates to hold a branch instruction conditional on a particular set of the status conditions. A decoder is connected to the instruction register and the circuit. A program counter is coupled to the decoder wherein the decoder is operable to enter a branch address into the program counter in response to the branch instruction when the particular set of the status conditions of the circuit are present.
