nonbeacon-enabled networks). The AT86RF230 parses this bit during RX_AACK
operation and transmits an acknowledgment frame if necessary.
Bit 6 the “Intra-PAN” subfield indicates that in a frame, where both, the destination and
source addresses are present, the PAN ID is omitted from the source address field.
This bit is evaluated by the AT86RF230 address filter logic when using RX_AACK
operation.
Bit [11:10] the “Destination address mode” subfield describes the format of the
destination address of the frame. The values of the address modes are summarized in
Table 8-2, according to IEEE 802.15.4-2003:
Table 8-2. IEEE 802.15.4-2003 Address Modes
If the destination address mode is either 2 or 3 (i.e. if the destination address is present
at all), it always consists of a 16-bit PAN ID first, followed by either the 16-bit or 64-bit
address as described by the mode.
Bit [15:14] form the “Source address mode” subfield, with a similar meaning as
“Destination address mode”.
The address field description bits of the FCF (Bits 6, 10, 11, 14, 15) affect the address
filter logic of the AT86RF230 while operating in RX_AACK states (see section 7.2.3.1).
The one-octet sequence number following the FCF identifies a particular frame, so that
duplicated frame transmissions can be detected. While operating in RX_AACK states,
the content of this field is copied from the frame to be acknowledged into the
acknowledgment frame.
The addressing fields terminate the MHR. The destination address (if present) is always
transmitted first, followed by the source address (if present). Each address consists of
the PAN ID and a device address. If both addresses are present, and the “Intra PAN”
subfield in the FCF is set to 1, the source PAN ID is omitted.
Note that in addition to these general rules, IEEE 802.15.4-2003 further restricts the
valid address combinations for the individual possible MAC frame types. For example,
the situation where both addresses are omitted (source addressing mode = 0 and
destination addressing mode = 0) is only allowed for acknowledgment frames. The
address filter in the AT86RF230 has been designed to apply to IEEE 802.15.4-2003
compliant frames only.
This is the actual MAC payload. It is usually structured according to the individual frame
type descriptions in IEEE 802.15.4-2003.
