FDVAL<7:0>: Frequency Deviation Value bits
The bits indicate single side frequency deviation (in bit value) in FSK Transmit mode.
FDVAL = 00000011 ≥ f
f
Where, FDVAL is the value in the register and has the range from 0 ≤ FDVAL ≤ 255. Refer to
Section 3.3.3 “fdev Setting in FSK Mode” and Section 3.3.4 “fdev Setting in OOK Mode” for
details on the f
Reserved: Reserved bit; do not use
0 = Reserved (default)
BRVAL<6:0>: Bit Rate Value bits
These bits set the bit rate (in bit value) of: Bit Rate = [ f
BRVAL<6:0> = 0000111 ≥ Bit Rate = 25 kbps NRZ (default)
Where, BRVAL is the value in the register and has the range from 0 ≤ BRVAL ≤ 127
