Description

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 as described in the specification
1 : Polarity is inverted as compared to the specification
Polarity of the output signal FIFOP.
0 : Polarity is as described in the specification
1 : Polarity is inverted as compared to the specification
Polarity of the SFD pin.
0 : Polarity is as described in the specification
1 : Polarity is inverted as compared to the specification
Polarity of the CCA pin.
FIFOP_THR sets the threshold in number of bytes in the
RXFIFO for FIFOP to go high.

The HSSD module is used as follows:
0: Off.
1: Output AGC status (gain setting / peak detector status /
accumulator value)
2: Output ADC I and Q values.
3: Output I/Q after digital downmix and channel filtering.
4: Reserved
5: Reserved
6: Input ADC I and Q values
7: Input DAC I and Q values.
The HSSD module requires that the FS is up and running as it
uses CLK_PRE (~150 MHZ) to produce its ~37.5 MHz data clock
and serialize its output words.
Multiplexer setting for the SFD pin.
Multiplexer setting for the CCA pin.

Description
The device part number. CC2420 has part number 0x002.
Gives the JEDEC manufacturer ID. The actual manufacturer ID
can be found in MANIFID[7:1], the number of continuation bytes
in MANFID[11:8] and MANFID[0]=1.
Chipcon's JEDEC manufacturer ID is 0x7F 0x7F 0x7F 0x9E
(0x1E preceeded by three continuation bytes.)
