ATmega2564/1284/644RFR2
Notes:
1. With RX_PDT_LEVEL ≥ 0x08, RSSI/ED can not resolve receiver input levels
from -80 dBm to -67 dBm.
2. During CCA or/and ED scan the ERD is disabled automatically.
9.8.10.2.4 PAM – PAN Address Match Recognition
ATmega2564/1284/644RFR2 PAM is activated with bit IPAN_RPC_EN of register
TRX_RPC set to one. PAM is automatically deactivated if RX override is enabled (see
Applicable to states: RX_AACK_ON
The indication of an address match fail of the IEEE 802.15.4 frame filtering (see
"Frame1. If the PAN address does not match, a new listen period starts immediately,
2. If the PAN address matches (but not the short destination address), the radio
transceiver enters power saving mode for the remaining frame. If acknowledgement
is also requested, power saving continues through the acknowledgement period. .
Notes:
1. PAM is applicable to short acknowledgement times and reserved frame types as
set by the bits AACK_ACK_TIME and AACK_FLTR_RES_FT of register
2. PAM is disabled automatically if promiscuous mode is enabled with bit
AACK_PROM_MODE in register XAH_CTRL_1) set to one..
9.8.10.2.5 Miscellaneous Power Reduction Functions
Applicable to states: RX_ON and RX_AACK_ON
automatically enters the power save mode.
Applicable to states: TX_ARET_ON
transaction, a random back-off period is performed. Within this back-off period the radio
transceiver automatically enters power saving mode.
Applicable to states: TX_ARET_ON and RX_AACK_ON
on page 47. The radio transceiver automatically enters power saving mode in:
TX_ARET: during the time waiting for an ACK frame, or
RX_AACK: during the time waiting for ACK transmission.
Note:
1. To handle nodes configured with a RX/TX turnaround time less than 12 symbols,
set RX_RPC_CTRL = 0 within TX_ARET state or set bit AACK_ACK_TIME of
register XAH_CTRL_1 to one.
