This bit enables the Multiple Address Filter 0. If the bit is set and the corresponding
Short Address and PAN ID Register is configured, an address match is indicated in the
IRQ_STATUS1 register and an interrupt occurs if the interrupt enable flag is set in the
IRQ_MASK register.

With this register, the behavior of the four independent Address Filters can be
configured.
Bit 7 – AACK_3_SET_PD - Set Data Pending bit for address filter 3.
Set the data pending subfield in Frame Control Field (FCF) for automatic frame
acknowledge. The content of AACK_SET_PD3 bit is copied into the frame pending
subfield of the acknowledgment frame if the ACK is the answer to a data request MAC
command frame.
Bit 6 – AACK_3_I_AM_COORD - Enable PAN Coordinator mode for address
filter 3.
This register bit has to be set if the node is a PAN coordinator for address filter 3. It is
used for frame filtering in RX_AACK. If set, the device acts as a PAN coordinator within
the filtered network, i.e. it responds to a null address. If the devices handles multiple
networks, it can operate as coordinator for one network and as a end node for the other
network simultaneously.
Bit 5 – AACK_2_SET_PD - Set Data Pending bit for address filter 2.
Set the data pending subfield in Frame Control Field (FCF) for automatic frame
acknowledge. The content of AACK_SET_PD2 bit is copied into the frame pending
subfield of the acknowledgment frame if the ACK is the answer to a data request MAC
command frame.
Bit 4 – AACK_2_I_AM_COORD - Enable PAN Coordinator mode for address
filter 2.
This register bit has to be set if the node is a PAN coordinator for address filter 2. It is
used for frame filtering in RX_AACK. If set, the device acts as a PAN coordinator within
