Description
Transmitter anti-aliasing filter cutoff frequency:
F
aliasing filters in kHz, F
and F is the integer value of the bit pattern in RXCFG13, which has a default value of 7.
TxInterpfilt default = 0111b, F
Transmitter output power (approx 3 dB steps):
000 → Max
001 → -3 dB
010 → -6 dB
011 → -9 dB
100 → -12 dB
101 → -15 dB
Others → not used

Description
Start pattern byte. This byte is sent second if two or more start pattern bytes are used.
Default: 00000000b
Description
Start pattern byte. This byte is sent third if three or more start pattern bytes are used.
Default: 00000000b
Description
Start pattern least significant byte. This byte is sent last if four start pattern bytes are used.
Default: 00000000b
Description
Start pattern most significant byte. This byte is sent first if one or more start pattern bytes are used.
