Description
Frequency deviation:
F
0 ≤ R ≤ 255
Description
Not used
BR = F
0 ≤ D ≤ 127 for FSK, 5 ≤ D ≤ 127 for OOK
Bit_Rate default = 7, BR = 25 kb/s for F
Description
OOK fixed threshold or minimum threshold in peak mode. Default is 6 dB.
00000000b → 0 dB
00000001b → 0.5 dB
00001100b → 6 dB
11111111b → 127 dB
Description
Configures the size of the FIFO:
00 → 16 bytes
01 → 32 bytes
10 → 48 bytes
11 → 64 bytes
Number of bytes to be written in the FIFO to activate the FIFO_Int_Tx and FIFO_Int_Rx interrupts.
Number of bytes = B + 1, where B is the register value.
FIFO_thresh default = 15, Number of bytes = 16
