Description
I&Q amplifiers:
0 -> disabled
1 -> enabled
SWParam configuration set selection:
0 -> configuration set defined by ConfigSwitch. SWITCH is an
output
1 -> configuration set defined by the pin SWITCH. SWITCH is
an input
Pattern recognition function:
0 -> disabled
1 -> enabled
Frequency band:
01 -> 433 – 435 MHz
10 -> 868 – 870 MHz
11 -> 902 – 928 MHz
Description
Frequency deviation Δf:
Δf =int( FSParan_Dev) * 1 kHz,
where int(x) = integer value of the binary representation of x.
Example:
00000001 -> Δf = 1 kHz
11111111 -> Δf = 255 kHz
OSR Mode (Oversampling Rate mode):
0 -> default Bit rate defined by FSParam_Br
1 -> variable OSR
Bit rate (when "FSParam_Change_Osr” = “0”):
Br = 152340/(int(FSParam_Br)+1),
where int(x) = integer value of the binary representation of x.
Example:
0000000 -> Br = 152.34 kbit/s
1111111 -> Br = 1.19 kbit/s
0000100 -> Br = 32.7 kbit/s used in Konnex mode
Define BR in terms of FSParam_BR and FS_Param_OSR:
FSParam_OSR = “00011101” and FSParam_Change_Osr =
‘1’ for Konnex standard
