If AACK_FLTR_RES_FT = 0, the received reserved frame is only checked for a valid
FCS.
• Bit 4 – AACK_UPLD_RES_FT
If AACK_UPLD_RES_FT = 1, received frames marked as reserved frames are further
processed. For these frames, interrupt IRQ_3 (TRX_END) is generated if the FCS is
valid.
In conjunction with the configuration bit AACK_FLTR_RES_FT = 1, these frames are
handled like IEEE 802.15.4 compliant data frames during RX_AACK transaction.
Otherwise, if AACK_UPLD_RES_FT = 0, frames with a reserved frame type are
blocked.
• Bit 3 – Reserved
• Bit 2 – AACK_ACK_TIME
According to IEEE 802.15.4-2006, section 7.5.6.4.2, the transmission of an
acknowledgment frame shall commence 12 symbol periods (aTurnaroundTime) after
the reception of the last symbol of a data or MAC command frame. This is achieved
with the reset value of the register bit AACK_ACK_TIME.
Alternatively, if AACK_ACK_TIME = 1, the acknowledgment response time is reduced
according to Table 5-24.
Table 5-24. Short ACK Response Time (AACK_ACK_TIME = 1)
The reduced ACK response time is particularly useful for the High Data Rate Modes,
refer to section 7.1.4.
• Bit 1 – AACK_PROM_MODE
Register bit AACK_PROM_MODE enables the promiscuous mode within the RX_AACK
mode; refer to IEEE 802.15.4-2006, section 7.5.6.5.
If this bit is set, incoming frames with a valid PHR generate interrupt IRQ_3
(TRX_END), even if the third level filter rules do not match or the FCS is not valid.
However, register bit RX_CRC_VALID (register 0x06) is set accordingly.
If a frame passes the third level filter rules, an acknowledgement frame is generated
and transmitted unless disabled by register bit AACK_DIS_ACK (register 0x2E,
CSMA_SEED_1).
• Bit 0 – Reserved
Register 0x2C (XAH_CTRL_0):
Register 0x2C (XAH_CTRL_0) is a control register for Extended Operating Mode.
