There are two different options for handling reserved frame types.
Short Acknowledgment Frame (ACK) Start Timing
Register bit AACK_ACK_TIME (register 0x17, XAH_CTRL_1), see
defines the symbol time between frame reception and transmission of an acknowledgment
frame.

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.
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.
AACK_UPLD_RES_FT = 0:
Any received frame indicated as a reserved frame is discarded.

0x10: acknowledges only frames with version
number 0 or 1 or 2
0x11: acknowledges all frames, independent of
the FCF frame version number
