    Many microcontrollers work exactly as you suggest; the 8051, for
    instance, does all those except I2C with shared circuitry... And
    firmware written for the Cypress Microsystems PSoC can
    dynamically  reconfigure a small number of digital blocks to
    provide all those functions and many more.
