Note
Note: In the following tables the POR column shows the default values of the command registers after power-on.
Configuration Setting Command
The resulting output frequency can be calculated as:
f
out
= f
0
(-1)
SIGN
* (M + 1) * (20 kHz)
where:
f
0
is the channel center frequency (see the
next command)
M is the three bit binary number <m2 : m0>
SIGN = (ms) XOR (FSK input)
The output power is given in the table as
relative to the maximum available power, which
depends on the actual antenna impedance.
