Combination Mode 11: Burst Modulation 1
Timer 2 mode 1/2:
12-bit compare counter/8-bit compare counter and 4-bit prescaler
Timer 2 output mode 1/6:
Timer 2 compare match toggles the output flip-flop (M2) to the
Timer 3
Timer 3 mode 6:
Carrier frequency burst modulation controlled by Timer 2 output
(M2)
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.
