Timer 2 output mode 1/6:
Timer 3 mode 6:
The Timer 3 counter is driven by an internal or external clock source. Its compare and compare
mode registers must be programmed to generate the carrier frequency with the output toggle
flip-flop. The output toggle flip-flop (M2) of Timer 2 is used to enable and disable the Timer 3 out-
put. The Timer 2 can be driven by the toggle output signal of Timer 3 (TOG3) or any other clock
source.
