TYPE

RESET

DESCRIPTION

Reserved

0x0

Defined on the transceiver version (CC1101).

6:4

MOD_FORMAT[2:0]

R/W

0x0

The modulation format of the radio signal:

The binary number is the setting and the result is the

modulation format.

000 = 2-FSK

001 = GFSK

010 = N/A

011 = ASK/OOK

100 = N/A

101 = N/A

110 = N/A

111 = MSK

The OOK/ASK pulse shaping feature is only supported for

output powers up to –1 dBm.

MSK is only supported for data rates above 26 kBaud.

MANCHESTER_EN

0x0

Enables Manchester encoding/decoding.

0 = Disable

1 = Enable

2:0

SYNC_MODE[2:0]

0x2

Combined sync-word qualifier mode.

The values 0 (000) and 4 (100) disables preamble and sync

word transmission. The values 1 (001), 2 (010), 5 (101) and 6

(110) enables 16-bit sync word transmission. The values 3

(011) and 7 (111) enables repeated sync word transmission.

The binary number is the setting and the result is the Sync-

word qualifier mode (for compatibility with the CC1101

transceiver).

000 = No preamble/sync word

001 = 15/16 sync word bits detected

010 = 16/16 sync word bits detected

011 = 30/32 sync word bits detected

100 = No preamble/sync, carrier-sense above threshold

101 = 15/16 + carrier-sense above threshold

110 = 16/16 + carrier-sense above threshold

111 = 30/32 + carrier-sense above threshold

DESCRIPTION

FEC_EN

R/W

0x2

Enable Forward Error Correction (FEC) with interleaving

for packet payload

0 = Disable

1 = Enable (Only supported for fixed packet length

mode, that is, PKTCTRL0.LENGTH_CONFIG=0)

6:4

NUM_PREAMBLE[2:0]

R/W

0x2

Sets the minimum number of preamble bytes to be

transmitted.

The binary number is the setting and the result is the

minimum number of preamble bytes to be transmitted.

000 = 2

001 = 3

010 = 4

011 = 6

100 = 8

101 = 12

110 = 16

111 = 24

3:2

Not Used.

1:0

CHANSPC_E[1:0]

R/W

0x2

2 bit exponent of channel spacing.
