Description
Reserved for future use.
The value of this register defines the conductance of the output
P-driver. This may be used to regulate the output power and
subsequently current consumption and operating distance.
Remark: The conductance value is binary weighted.
Description
Reserved for future use.
The value of this register defines the conductance of the output
P-driver for the time of modulation. This may be used to regulate the
modulation index.
Remark: The conductance value is binary weighted.
