Description

Transmitter output power:

0 0 -> 0 dBm

0 1 -> 5 dBm

1 0 -> 10 dBm

1 1 -> 15 dBm

Source for the reference frequency:

0 -> on-chip crystal oscillator

1 -> external signal

Receiver wake-up type selection

0 -> “Boost” power up sequence

1 -> Standard power-up sequence

Pre-filtering of bit stream in

transmitter mode:

0 -> no filtering; 1 -> filtering

Selection of the FEI block:

0 -> FEI uses FFD demodulator

1 -> FEI uses correlators

Rise and fall time when

RTParam_Filter = 1:

0 -> 10 % of bit duration

1 -> 20 % of bit duration

Inhibition of the modulation in

transmitter mode:

0 -> modulation; 1 -> no modulation

Range of the RSSI:

0 -> low range; 1 -> high range

Enable CLKOUT output:

0 -> no signal on pad CLKOUT

1 -> clock signal available on

CLKOUT at 9.75 down to 1.22 MHz

(39MHz divided by 4, 8, 16 or 32)
