5.6.2 Indication of wireless transmitting

Buffer (empty): the internal 400 bytes data in the buffer are written to the RFIC (Auto sub-packaging). When AUX=1, the user

can input data less than 400 bytes continuously without overflow. Buffer (not empty): when AUX=0, the internal 400 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.

Only happened when power-on resetting or exiting sleep mode



No.

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 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

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.
