Address matching, indicated by interrupt IRQ_5 (AMI), is furthermore controlled by the
FCF of a received frame according to the following rule: If Destination Addressing Mode
is 0/1 and Source Addressing Mode is 0 (see section 6.1.2.2), no interrupt IRQ_5 is
generated. This causes that no acknowledgement frame is announced.
For backward compatibility with IEEE 802.15.4-2003, the third level filter rule 2 (Frame
Version) can be disabled by register bits AACK_FVN_MODE (register 0x2E,
CSMA_SEED_1).
Frame filtering is available in Extended and Basic Operating Modes. A frame that
passes the Frame Filter generates the interrupt IRQ_5 (AMI) if not masked.

6.2.1 Configuration
The Frame Filter is configured by setting the appropriate address variables and several
additional properties as described in Table 6-6.

Frame acceptance criteria depending on
FCF frame version number
b00: Accept only frames with version
number 0, i.e. according to
IEEE 802.15.4-2003 frames
b01: Accept only frames with version
number 0 or 1, i.e. frames according to
IEEE 802.15.4-2006
b10: Accept only frames with version
number 0 or 1 or 2
b11: Accept all frames, independent of the
FCF frame version number
