1110 = 676 kHz
1101 = 514 kHz
1100 = 458 kHz
1011 = 414 kHz
1010 = 378 kHz (default)
1001 = 321 kHz
1000 = 262 kHz
0111 = 234 kHz
0110 = 211 kHz
0101 = 184 kHz
0100 = 157 kHz
0011 = 137 kHz
0010 = 109 kHz
0001 = 82 kHz
0000 = 65 kHz
BUTFILV<3:0>: Butterworth Filter Value bits
These bits set the receiver bandwidth both in FSK and OOK mode.
