4.4. FSK Control
For detailed instructions on FSK signal generation, refer to “AN32: FSK Generation”. These registers support
enhanced FSK generation mode, which is enabled by setting FSKEN = 1 (direct Register 108, bit 6) and REL = 1
(direct Register 32, bit 6).

DC-DC Converter V
This register sets the overhead voltage, V
When the VOV bit = 0 (direct Register 66, bit 4), V
(VMIND = 0 to 6h). When the VOV bit = 1, V
(VMIND = 0 to 9h).
Loop Closure Threshold—Lower Bound.
This register defines the lower threshold for loop closure hysteresis, which is enabled in
bit 0 of direct Register 108. The range is 0–80 mA in 1.27 mA steps.
