1. A microcontroller comprising:

  • an execution unit for executing instructions; and

    an asynchronous serial port for communicating asynchronous frames having a frame length, each frame comprising at least one data bit and an address bit, wherein the asynchronous serial port is selectably configurable by the execution unit to communicate either n or n−

    1 data bits, for n greater than 1, prior to an address bit, the placement of the address bit being independent of frame length.
