AUX=0, the internal 512 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 Reset and exit sleep mode
5.6.4 Notes for AUX
For function 1 & function 2 mentioned above, the priority should be given to the one with low level output, which
means if it meets each of any low level output condition, AUX outputs low level, if none of the low level con dition 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 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 effected immediately.
When the user switches to other operating modes from mode 3 (sleep mode) or it ’s still in reset process, the module
will reset user parameters, during which AUX outputs low level.
