Description
Reserved, write as 0
Accept all beacon frames when address recognition is enabled.
This bit should be set when the PAN identifier programmed into
CC2420 RAM is equal to 0xFFFF and cleared otherwise. This bit
is don't care when MDMCTRL0.ADR_DECODE = 0.
0 : Only accept beacons with a source PAN identifier which
matches the PAN identifier programmed into CC2420 RAM
1 : Accept all beacons regardless of the source PAN identifier
Polarity of the output signal FIFO.
0 : Polarity is active high
1 : Polarity is active low
Polarity of the output signal FIFOP.
0 : Polarity is active high
1 : Polarity is active low
Polarity of the SFD pin.
0 : Polarity is active high
1 : Polarity is active low
Polarity of the CCA pin.
0 : Polarity is active high
1 : Polarity is active low
FIFOP_THR sets the threshold in number of bytes in the
RXFIFO for FIFOP to go active.
