ABSTRACT:
A digital processor may be coupled to a processor programmer through a single conductor programming bus. The digital processor and the processor programmer, each may have a single programming connection (e.g., terminal, pin, etc.) coupled to the single conductor programming bus. The processor programmer may comprise an instruction encoder/decoder, a Manchester encoder, a Manchester decoder, a bus receiver and a bus transmitter. The bus receiver and bus transmitter may be coupled to the single connection that may be coupled to the single conductor programming bus. The instruction encoder/decoder may be coupled to a programming console, e.g., a personal computer, workstation, etc. The digital processor may comprise an instruction encoder/decoder, a Manchester encoder, a Manchester decoder, a bus receiver, a bus transmitter, a central processing unit (CPU), and a program memory. The bus receiver and bus transmitter may be coupled to the single connection, e.g., terminal, pin, ball, etc., on an integrated circuit package containing the digital processor. The single connection may be coupled to the single conductor programming bus. The instruction encoder/decoder may be coupled to the CPU and the program memory.
