Register 0x2E (CSMA_SEED_1):
The CSMA_SEED_1 register contains a part of the CSMA seed for the CSMA-CA
algorithm, as well as control bits for the Frame Filter and RX_AACK transaction.
Table 5-27. Register 0x2E (CSMA_SEED_1)
• Bit 7:6 – AACK_FVN_MODE
The frame control field of the MAC header (MHR) contains a frame version subfield.
The setting of AACK_FVN_MODE specifies the frame filtering and acknowledgement
behavior of the AT86RF212. According to the content of these register bits, the radio
transceiver passes frames with a specific frame version number, number group, or
independent of the frame version number.
Thus, the register bit AACK_FVN_MODE defines the maximum acceptable frame
version. Received frames with a higher frame version number than configured do not
pass the Frame Filter and thus are not acknowledged.
Table 5-28. Frame Version Subfield dependent Frame Acknowledgment
Note that the frame version field of the acknowledgment frame is set to 0x00 according
to IEEE 802.15.4-2006, section 7.2.2.3.1 “Acknowledgment frame MHR fields”.
• Bit 5 – AACK_SET_PD
The content of AACK_SET_PD 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.
In addition, if register bits AACK_FVN_MODE (register 0x2E, CSMA_SEED_1) are
configured to accept frames with a frame version other than 0 or 1, the content of
register bit AACK_SET_PD is also copied into the “Frame Pending” subfield of the
acknowledgment frame for any MAC command frame with a frame version of 2 or 3 that
have the security enabled subfield set to 1. This is done in the assumption that a future
version of the standard [2] might change the length or structure of the auxiliary security
header, so it would not possible to safely detect whether the MAC command frame is
actually a data request command or not.
