AT86RF212
5.2.3.1 Configuration Registers
RX_AACK configuration as described below shall be done prior to switching the
AT86RF212 into state RX_AACK_ON, refer to section 5.2.1.
Table 5-8 summarizes all register bits which affect the behavior of an RX_AACK
transaction. For frame filtering it is further required to setup address registers to match
to the expected address.

The usage of the RX_AACK configuration bits for various device types or operating
modes is explained in the following sections. Configuration bits not mentioned in the
following two sections should be set to their reset values according to Table 11-2.
5.2.3.2 Configuration of IEEE Compliant Scenarios
Device not operating as a PAN Coordinator
Table 5-9 shows the RX_AACK configuration registers, required to setup a typical
IEEE 802.15.4 compliant device.
