4.5. FSK Control
For detailed instructions on FSK signal generation, refer
to “Application Note 32: FSK Generation” (AN32).
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).

FSK Amplitude Coefficient for Space.
When FSKEN = 1 and REL = 1, this register sets the amplitude to be used when gener-
ating a space or “0”. When the active timer (OAT1) expires, the value of this register is
loaded into oscillator 1 instead of OSC1X.
FSK Frequency Coefficient for Space.
When FSKEN = 1 and REL = 1, this register sets the frequency to be used when gener-
ating a space or “0”. When the active timer (OAT1) expires, the value of this register is
loaded into oscillator 1 instead of OSC1.
FSK Amplitude Coefficient for Mark.
When FSKEN = 1 and REL = 1, this register sets the amplitude to be used when gener-
ating a mark or “1”. When the active timer (OAT1) expires, the value of this register is
loaded into oscillator 1 instead of OSC1X.
FSK Frequency Coefficient for Mark.
When FSKEN = 1 and REL = 1, this register sets the frequency to be used when gener-
ating a mark or “1”. When the active timer (OAT1) expires, the value of this register is
loaded into oscillator 1 instead of OSC1.
FSK Transition Parameter from 0 to 1.
When FSKEN = 1 and REL = 1, this register defines a gain correction factor that is
applied to signal amplitude when transitioning from a space (0) to a mark (1).
FSK Transition Parameter from 1 to 0.
When FSKEN = 1 and REL = 1, this register defines a gain correction factor that is
applied to signal amplitude when transitioning from a mark (1) to a space (0).
