   * \brief CryptoAuthLib Basic API methods for Counter command.
   *
   * The Counter command reads or increments the binary count value for one of the
   * two monotonic counters
   *
   * \note List of devices that support this command -  ATECC508A and ATECC608A.
   *       There are differences in the modes that they support. Refer to device
   *       datasheets for full details.
