Figure 13.2 shows an example of the 8-bit timer being used to generate a pulse output with a
desired duty cycle. The control bits are set as follows:
1. In TCR, clear bit CCLR1 to 0 and set bit CCLR0 to 1 so that TCNT is cleared at a TCORA
2. In TCSR, set bits OS3 to OS0 to B'0110, causing the output to change to 1 at a TCORA
With these settings, the 8-bit timer provides pulses output at a cycle determined by TCORA with a
pulse width determined by TCORB. No software intervention is required. The output level of the
8-bit timer holds 0 until the first compare match occurs after a reset.
