To wake up external MCU
5.6.2 Indication of wireless transmitting
 Buffer (empty): the internal 512 bytes data in the buffer are written to the RFIC (Auto sub-packaging).
 When AUX=1, the user can input data less than 512 bytes continuously without overflow. Buffer (not empty): when
AUX=0, the internal 512 bytes data in the buffer have not been written to the RFIC complete ly. 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 sub package.
 When AUX = 1, it does not mean that all the UART data of the module have been transmitted already, perhaps the
last packet of data is still in transmission.
5.6.3 Configuration procedure of module
