Pulse Output with Arbitrary Duty Cycle

Figure 11.9 shows an example of output of pulses with an arbitrary duty cycle.

1. Set bits CCLR1 and CCLR0 in TCRV0 so that TCNTV will be cleared by compare match with

TCORA.

2. Set bits OS3 to OS0 in TCSRV so that the output will go to 1 at compare match with TCORA

and to 0 at compare match with TCORB.

3. Set bits CKS2 to CKS0 in TCRV0 and bit ICKS0 in TCRV1 to select the desired clock source.

4. With these settings, a waveform is output without further software intervention, with a period

determined by TCORA and a pulse width determined by TCORB.
