  /**
   * \defgroup me Table-driven Manchester encoding and decoding
   *
   * Manchester encoding is a bit encoding scheme which translates each
   * bit into two bits: the original bit and the inverted bit.
   *
   * Manchester encoding is used for transmitting ones and zeroes
   * between two computers. The Manchester encoding reduces the receive
   * oscillator drift by making sure that no consecutive ones or zeroes
   * are ever transmitted.
   *
   * The table driven method of Manchester encoding and decoding uses
   * two tables with 256 entries. One table is a direct mapping of an
   * 8-bit byte into a 16-bit Manchester encoding of the byte. The
   * second table is a mapping of a Manchester encoded 8-bit byte to 4
   * decoded bits.
