5.6.2 Indication of wireless transmitting

Buffer (empty): the internal 1000 bytes data in the buffer are written to the RFIC (Auto sub-packaging). When AUX=1, the user
can input data less than 1000 bytes continuously without overflow. Buffer (not empty): when AUX=0, the internal 1000 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 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

Only happened when power-on resetting or exiting sleep mode

5.6.4 Notes for AUX

No.
For function 1 & function 2 mentioned above, the priority should be given to the one with low level output, which means if it
1 meets each of any low level output condition, AUX outputs low level, if none of the low level condition is met, AUX outputs
high level.
When AUX outputs low level, it means the module is busy & cannot conduct operating mode checking. Within 1ms since AUX
2
outputs high level, the mode switch will be completed.
After switching to new operating mode, it will not work in the new mode immediately until AUX rising edge lasts for 2ms . If
3
AUX stays on the high level, the operating mode switch can be effected immediately.
