MODSEL<1:0>: Modulation Type Selection bits
These bits set the type of modulation to be used in Sub-GHz range.
11 = Reserved
10 = FSK (default)
01 = OOK
00 = Reserved
DMODE0: Data Mode 0 bit
Setting this bit selects the data operational mode as LSB. Use this bit with DMODE1 to select the
operational mode.
0 = Default
OOKTYP<1:0>: OOK Demodulator Threshold Type bits
The combination of these bits selects the Demodulator Threshold Type for operation.
11 = Reserved
10 = Average Mode
01 = Peak Mode (default)
00 = Fixed threshold mode
DMODE1: Data Mode 1 bit
Setting this bit selects the data operational mode as MSB. Use this bit with DMODE0 to select the
operational mode.
0 = Default
IFGAIN<1:0>: IF Gain bits.
Selects gain on the IF chain.
11 = -13.5 dB
