Figure 6-55. FSK Modulation
Combination Mode 7: Pulse-width Modulation (PWM)
SSI mode 1:
Timer 3 mode 9:
The two compare registers are used to generate two varied time intervals. The SSI data output
selects which compare register is used for the output pulse generation. In this mode, both com-
pare and compare mode registers must be programmed to generate the two pulse width. It is
also useful to enable the single-action mode for extreme duty cycles. Timer 2 is used as baud-
rate generator and for the triggered restart of Timer 3. The SSI must be supplied with the toggle
signal of Timer 2. The counter is driven by an internal or external clock source.
