Figure 11.3 shows an example for outputting an arbitrary duty pulse.
1. Clear the CCLR1 bit in TCR to 0 and then set the CCLR0 bit to 1 so that TCNT is cleared
2. Set the OS3 to OS0 bits in TCSR to B'0110 so that 1 is output according to the compare match
According to the above settings, the waveforms with the TCORA cycle and TCORB pulse width
can be output without the intervention of software.
