Buffer (empty): the internal 80 bytes data in the buffer are written to the RFIC (Auto subpackage). When AUX=1,
the user can input data less than 80 bytes continuously without overflow.
Buffer (not empty): when AUX=0, the internal 80 bytes data in the buffer have not been written to the RFIC
completely. If the user starts to transmit data at this circumstance, it may cause overtime when the module is
waiting for the user data, or transmitting wireless subpackage.

Notes: When AUX = 1, it does not mean that all the UART data of the module have been transmitted already,
