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
2. In the TCSR, bits OS3 to OS0 are set to “0110,” causing the output to change to “1” on
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.
cleared when its value matches the constant in TCORA.
