Each channel in the 8-bit timer can generate three types of interrupts: compare-match A and B
(CMIA and CMIB), and overflow (OVI). Each interrupt can be enabled or disabled by an enable
bit in TCR. Independent signals are sent to the interrupt controller for each interrupt. Table 9.3
lists information about these interrupts.

In the example below, the 8-bit timer is used to generate a pulse output with a selected duty cycle.
The control bits are set as follows:
1. In TCR, CCLR1 is cleared to 0 and CCLR0 is set to 1 so that the timer counter is cleared when
2. In TCSR, bits OS3 to OS0 are set to 0110, causing the output to change to 1 on compare-match
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.
