Section 13 8-Bit Timers (TMR)

13.4.1
Figure 13.2 shows an example in which 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, the CCLR1 bit is cleared to 0 and the CCLR0 bit is set to 1 so that TCNT is cleared at
[2] In TCSR, the OS3 to OS0 bits are set to B'0110, causing the output to change to 1 at a TCORA
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.
