Function
These bits are used to perform special operations on the
frame type field of a received packet. These operations do
not influence the packet that is written to the RXFIFO.
00 : Leave frame type as it is.
01 : Invert MSB of frame type.
10 : Set MSB of frame type to 0.
11 : Set MSB of frame type to 1.
For IEEE 802.15.4 compliant operation these bits should
always be set to 00.
Mode for accepting reserved IEEE 802.15.4 frame types
when address recognition is enabled
(MDMCTRL0.ADDR_DECODE = 1).
0 : Reserved frame types (100, 101, 110, 111) are rejected
by address recognition.
1 : Reserved frame types (100, 101, 110, 111) are always
accepted by address recognition. No further address
decoding is done.
When address recognition is disabled
(MDMCTRL0.ADDR_DECODE = 0), all frames are received and
RESERVED_FRAME_MODE is don’t care.
For IEEE 802.15.4 compliant operation these bits should
always be set to 00.
PAN Coordinator enable. Used for filtering packets with no
destination address, as specified in section 7.5.6.2 in
802.15.4 [1]
0 : Device is not a PAN Coordinator
1 : Device is a PAN Coordinator
Hardware Address decode enable.
0 : Address decoding is disabled
1 : Address decoding is enabled
CCA Hysteresis in dB, values 0 through 7 dB
