Set Channel Mask (0x03)
The Channel Mask is used by the MAC when performing an initial scan for existing 802.15.4 radios in
its immediate vicinity. A Channel bit set to one(1) enables that channel to be scanned. Channel bits
set to zero(0) are skipped during the scan.
When powering-up or after a reset, the End Device will always scan the channels in the channel mask
for its associated coordinator. The Coordinator, when restarted, will use the Default Channel for its
operating channel.
