The 4-bit stage and the 8-bit stage work together as a 12-bit compare counter. A com-
pare match signal of the 4-bit and the 8-bit stage generates the signal for the counter
reset, toggle flip-flop or interrupt. The compare action is programmable via the compare
mode register (T2CM). The 4-bit counter overflow (OVF1) supplies the clock output
(POUT) with clocks. The duty cycle generator (DCG) has to be bypassed in this mode.
