XXXX
Where XXXX represents a 16-bit decimal
number enabling IEEE 802.15.4 channel
numbers 11 to 26.
Writing a bit to 1 enables a channel and
subsequently writing a bit to 0 disables a
channel for scanning, joining and establishing
networks.
e.g. when setting S00 to 0001, only channel 11
will be used for all following operations.

Entering a value higher than 3 will automatically
enable boost mode regardless of the setting of
bit E of S11.
