ATmega2564/1284/644RFR2
If the bit RX_RPC_EN is set, the receiver is periodically in power-save during all RX
states to reduce the current consumption while listening for incoming signals. Note: this
feature causes a sensitivity loss of approximately 2 dB.
Bit 4 – PDT_RPC_EN - Smart Receiving Mode Reduced Sensitivity Enable
If the bit PDT_RPC_EN is set, the RX sensitivity is reduced and the current
consumption is decreased. Note that together with this setting the value of the register
RX_PDT_LEVEL should be adapted.
Bit 3 – PLL_RPC_EN - PLL Smart Receiving Mode Enable
If bit PLL_RPC_EN is set, the PLL is in power-save during the transceiver states
PLL_ON or TX_ARET_ON while no frame transmission has been initiated.
Bit 2 – Res0 - Reserved
Bit 1 – IPAN_RPC_EN - Smart Receiving Mode IPAN Handling Enable
If the bit IPAN_RPC_EN is set, RPC for IPAN is enabled. This causes a transceiver
power-save while receiving a frame with matching PAN but not matching address. Note
that an enabled RX override feature will automatically disable the IPAN_RPC_EN
function.
Bit 0 – XAH_RPC_EN - Smart Receiving in Extended Operating Modes Enable
If the bit XAH_RPC_EN is set, RPC functionality for the Extended Operating Mode is
enabled. This reduces the PLL power consumption during the CSMA/CA back-off time,
a transmit/receive turnaround in TX_ARET state or an active frame protection
(RX_SAFE_MODE).
