RESERVED_FRAME_MODE
0
R/W
Mode for accepting reserved IEE 802.15.4 frame types when
address recognition is enabled (
MDMCTRL0.ADR_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.ADR_DECODE =
0
), all frames are received and
RESERVED_FRAME_MODE
is don’t
care.
12
PAN_COORDINATOR
0
R/W
Should be set high when the device is a PAN Coordinator. Used
for filtering packets with no desitination address, as speccified in
section 7.5.6.2 in 802.15.4, D18

ADR_DECODE
1
R/W
Hardware Address decode enable.
0 : Address decoding is disabled
1 : Address decoding is enabled

AUTOCRC
1
R/W
In packet mode a CRC-16 (ITU-T) is calculated and is
transmitted after the last data byte in TX. In RX CRC is
calculated and checked for validity.
4
AUTOACK
0
R/W
If AUTOACK is set, all packets accepted by address recognition
with the acknowledge request flag set and a valid CRC are
ack’ed 12 symbol periods after being received.
3:0
PREAMBLE_LENGTH
[3:0]
2
R/W
The number of preamble bytes (2 zero-symbols) to be sent in TX
mode prior to the SYNCWORD, encoded in steps of 2. The reset
value of 2 is compliant with IEEE 802.15.4, since the 4
zero
byte is included in the SYNCWORD.
0 : 1 leading zero bytes (not recommended)
1 : 2 leading zero bytes (not recommended)
2 : 3 leading zero bytes (IEEE 802.15.4 compliant)
3 : 4 leading zero bytes
…
15 : 16 leading zero bytes
