Timer 2 mode 1/2:
Timer 2 output mode 1/6: Timer 2 compare match toggles the output flip-flop (M2)
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 output. The Timer 2 can be driven by the toggle output signal of
Timer 3 (TOG3) or any other clock source.
