Promiscuous Mode
The promiscuous mode is described in IEEE 802.15.4-2006, section 7.5.6.2. This mode is fur-
ther illustrated in
mode, the MAC sub layer shall pass received frames with correct FCS to the next higher layer
and shall not be processed further. That implies that frames should never be acknowledged.

If a network should only allow access to nodes which use the IEEE 802.15.4-2003,
then AACK_FVN_MODE should be set to 0.
If a device should acknowledge all frames independent of its frame version,
AACK_FVN_MODE should be set to 3. However, this can result in conflicts with
co-existing IEEE 802.15.4-2006 standard compliant networks.

Description
Set node addresses
0: disable frame protection
1: enable frame protection
0: if transceiver works in unslotted mode
1: if transceiver works in slotted mode
1: device is PAN coordinator
0: frame pending subfield is not set in FC
1: frame pending subfield is set in FCF
Controls the ACK behavior, depending on FCF

number 0, i.e. according to IEEE 802.15.4-2003
frames
0x01: acknowledges only frames with version
number 0 or 1, i.e. frames according to IEEE
802.15.4-2006
0x10: acknowledges only frames with version
number 0 or 1 or 2
0x11: acknowledges all frames, independent of
the FCF frame version number
