AACK_FVN_MODE
Controls the ACK behavior, depends on
FCF frame version number.
0x00 : Acknowledges only frames with
version number 0, that is according to
IEEE 802.15.4-2003 frames.
0x01 : Acknowledges only frames with
version number 0 or 1, that is frames
according to IEEE 802.15.4-2006.
0x10 : Acknowledges only frames with
version number 0 or 1 or 2.
0x11 : Acknowledges all frames,
independent of the FCF frame version
number.
There are three different options for handling reserved frame types.
1. AACK_UPLD_RES_FT = 1, AACK_FLT_RES_FT = 0:
Any non-corrupted frame with a reserved frame type is indicated by an
IRQ_3 (TRX_END) interrupt. No further address filtering is applied on those frames.
An IRQ_5 (AMI) interrupt is never generated and the acknowledgment subfield is
ignored.
2. AACK_UPLD_RES_FT = 1, AACK_FLT_RES_FT = 1:
If AACK_FLT_RES_FT = 1 any frame with a reserved frame type is filtered by the
address filter similar to a data frame as described in the standard. This implies the
generation of the
IRQ_5 (AMI)
interrupts upon address match. An
IRQ_3 (TRX_END) interrupt is only generated if the address matched and the frame
was not corrupted. An acknowledgment is only send, when the ACK request subfield
was set in the received frame and an IRQ_3 (TRX_END) interrupt occurred.
3. AACK_UPLD_RES_FT = 0:
Any received frame with a reserved frame type is discarded.
