Name Addr Prot Description
Configure FIFO use
Bit 0: AUTOFLUSH_IGN

number in the Rx FIFO.
0: Keep
1: Auto-flush
Bit 1: AUTOFLUSH_CRC
Keep received packets with CRC error in the Rx
FIFO.
0: Keep
1: Auto-flush
Bit 2: AUTOFLUSH_EMPTY
Keep packets with no payload in the Rx FIFO.
0: Keep
1: Auto-flush
Bit 3: RX_STATUS_CONF
Rx FIFO channel information
0: Do not append RSSI and RES
1: Append RSSI and RES
Bits 4–5: RX_ADDR_CONF
0x6002 Sem1
PRF_FIFO_CONF
Rx FIFO address and config byte configuration
00: Do not include address or config byte in Rx
FIFO
01: Include received address in Rx FIFO (1-byte
addresses only), but no config byte
10: Include config byte in Rx FIFO, but no address
byte
11: Include received address (1-byte addresses
only) and config byte in Rx FIFO
Bits 6–7: TX_ADDR_CONF
Tx FIFO address and config byte configuration
00: No address or config byte; read address from
PRF_ADDR_ENTRY0
01: Include address byte in Tx FIFO, no config byte
10: Include config byte and use address index in
that byte to find address from
PRF_ADDR_ENTRYn
11: Read address from Tx FIFO followed by config
byte (where address information is ignored). Not
allowed for PRF_TASK_CONF.MODE = 00 or
01.
Packet configuration
Bit 0: ADDR_LEN. Number of address bytes (0 or
1).
Bit 1: AGC_EN

1: Use AGC (Section 25.9.2.1)
0x6003 Sem0
PRF_PKT_CONF
Bit 2: START_TONE
0: Ordinary transmission
1: Override extra preamble bytes with tone and
reduce synthesizer calibration time accordingly
(Section 25.9.2.2)
Bits 3-7: Reserved, always write 0.
0x6004 Sem1 Number of CRC bytes. Permitted values: 0–4
PRF_CRC_LEN
For transmit on clear channel. Start a transmit task
by listening to the channel; start transmitting if the
0x6005 Sem1
PRF_RSSI_LIMIT
RSSI drops below the level (signed) given in this
register.
For transmit on clear channel. Number of additional
0x6006–0x6007 Sem1 RSSI measurements that must be below the RSSI
PRF_RSSI_COUNT
limit before transmission takes place.
