Bit Field Name
7:0 FREQ[7:0]
0xDF0B: FREQ0 – Frequency control word, low byte
Reset
R/W Description
0xEC
R/W Ref. FREQ2 register
Bit Field Name
7:6 CHANBW_E[1:0]
5:4 CHANBW_M[1:0]
3:0 DRATE_E[3:0]
0xDF0C: MDMCFG4 – Modem configuration

R/W
R/W Sets the decimation ratio for the delta-sigma ADC input
stream and thus the channel bandwidth.
BW_channel
=
f _XOSC
8 ⋅ (4 + CHANBW _ M )·2^CHANBW
_E
The default values give 203kHz channel filter bandwidth,
assuming a 26.0MHz crystal.
R/W The exponent of the user specified symbol rate
Bit Field Name

0xDF0D: MDMCFG3 – Modem configuration
Reset
R/W Description
0x22
R/W The mantissa of the user specified symbol rate. The symbol
rate is configured using an unsigned, floating-point number
with 9-bit mantissa and 4-bit exponent. The 9^th bit is a
hidden ‘1’. The resulting data rate is:
( ) _{RDATA =}
256 + DRATE _ M
2²⁸
⋅ 2^{DRATE _ E} _{⋅ f XOSC}
The default values give a data rate of 115.051kbps (closest
setting to 115.2kbps), assuming a 26.0MHz crystal.
