transaction. For address filtering it is further required to setup address registers to
match the expected address.
Configuration and address bits are to be set in TRX_OFF or PLL_ON state prior to
switching to RX_AACK mode.
A graphical representation of various operating modes is illustrated in
Table 7-5. Overview of RX_AACK Configuration Bits.
The usage of the RX_AACK configuration bits for various operating modes of a node is
explained in the following sections. Configuration bits not mentioned in the following two
sections should be set to their reset values according to
All registers mentioned in
The general behavior of the “Atmel AT86RF232 Extended Feature Set”,
settings:
are completely independent from RX_AACK mode and can be arbitrarily combined.

Description
Set node addresses.
Protect buffer after frame reception.
Support promiscuous mode.
Change auto acknowledge start time.
Enable reserved frame type reception,
needed to receive non-standard compliant
frames.
Filter reserved frame types like data frame
type, needed for filtering of non-standard
compliant frames.
If set, acknowledgment transmission has
to be triggered by pin 11 (SLP_TR)
If set, the device is a PAN coordinator,
that is responds to a null address.
Disable generation of acknowledgment.
