11.5 Sample Application
In the example below, the 8-bit timer is used to generate a pulse output with a selected duty factor.
The control bits are set as follows:
1. In the TCR, CCLR1 is cleared to 0 and CCLR0 is set to 1 so that the timer counter is cleared
2. In the TCSR, bits OS3 to OS0 are set to “0110,” causing the output to change to 1 on compare-
With these settings, the 8-bit timer provides output of pulses at a rate determined by TCORA with
a pulse width determined by TCORB. No software intervention is required.
when its value matches the constant in TCORA.
