Note All changes to the APPLICATION parameters must be performed when the device is in Sleep mode, with the
exception of DA(15). Mode can be sequentially written to “1”, and then “0” while the device is in Transmit mode, to
speed up the turn off process and circumvent the TOFFT delay.

If done in Sleep mode, the Frequency change instruction will be applied next time the RFM68W is turned on. If Frequency
change occurs during transmission, the automated Frequency Hopping sequence described in section [4.4.2] will take
place.
