Table 10 APPLICATION Configuration Parameters
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.

Table 11 FREQUENCY Configuration Parameters
If done in Sleep mode, the Frequency change instruction will be applied next time the RFM68CW is turned on. If
Frequency change occurs during transmission, the automated Frequency Hopping sequence described in section [4.4.2]
will take place.
