After writing the BitScrambler program, we can enable it by calling :cpp:func:`parlio_tx_unit_decorate_bitscrambler`. And configure the :cpp:member:`parlio_transmit_config_t::bitscrambler_program` to point to the binary file of the BitScrambler program. Different transmission transactions can use different BitScrambler programs. The binary file must conform to the BitScrambler assembly language specification, and will be loaded into the BitScrambler's instruction memory at runtime. For details on how to write and compile the BitScrambler program, please refer to :doc:`BitScrambler Programming Guide </api-reference/peripherals/bitscrambler>`.

.. note::
Due to hardware limitations, the bitstream generated by the BitScrambler cannot change the length compared to the original bitstream, otherwise transmission blocking or data loss may occur.
:cpp:func:`parlio_tx_unit_decorate_bitscrambler` and :cpp:func:`parlio_tx_unit_undecorate_bitscrambler` need to be used in pairs. When deleting the TX unit, you need to call :cpp:func:`parlio_tx_unit_undecorate_bitscrambler` first to remove the BitScrambler.
