CL2/1
The 4-bit stage and the 8-bit stage work together as a 12-bit compare counter. A compare 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 gen-
erator (DCG) has to be bypassed in this mode.
