Description

00010

Pre-filtering of the bit stream in transmitter mode

0 -> no filtering

1 -> filtering

The filtering function is available only for the following bit

rates and frequency deviations:

FSPanam_Br = "1111110" -> BR = 1200 bps

FSPanam_Br = "0111111" -> BR = 2400 bps

FSPanam_Br = "0011111" -> BR = 4800 bps

FSPanam_Br = "0001111" -> BR = 9600 bps

FSPanam_Br = "0000111" -> BR = 19200 bps

FSPanam_Br = "0000011" -> BR = 38400 bps

FSPanam_Br = "0000001" -> BR = 76800 bps

FSParam_Dev = "00101000" -> ∆f = 40 kHz

FSParam_Dev = "00110111" -> ∆f = 55 kHz

FSParam_Dev = "01010000" -> ∆f = 80 kHz

FSParam_Dev = "10100000" -> ∆f = 160 kHz

FSParam_Dev = "11001000" -> ∆f = 200 kHz

5

00010

Inhibition of the modulation in transmitter mode:

0 -> modulation

1 -> no modulation

4

00010

IQ amplifiers on/off:

0 -> off

1 -> on

3

00010

Mode of switch:

0 -> configuration defined by Chip_config and pad SWITCH

is an output that indicates the RX or TX mode of the chip

1 -> configuration defined by the pad SWITCH used as an

input

2

00010

Pattern recognition on/off:

0 -> off

1 -> on
