® 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.
0- RXD
1- TXD
2- AUX
563
Subpackage transmitting : the last package of data have been
written to the RFIC. When transmission is on, user can continue
to input 512 new bytes. (The buffer is actually empty.)

5.6.4 Notes for AUX
No. Description
For function 1 & function 2 mentioned above, the priority should be given to the one with low level output, which means if
1 it 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
2 AUX 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 AUX stays on the high level, the operating mode switch can be affected immediately.
When the user switches to other operating modes from mode 3 (sleep mode) or it's still in reset process, the module will
4 reset user parameters, during which AUX outputs low level.
