12.4.1
Figure 12.2 shows an example of arbitrary duty pulse output.
1. Set TCR in CCR1 to 0 and CCLR0 to 1 to clear TCNT by a TCORA compare-match.
2. Set OS3 to OS0 bits in TCSR to B'0110 to output 1 by a compare-match A and 0 by compare-
By the above settings, waveforms with the cycle of TCORA and the pulse width of TCRB can be
output without software intervention.

Description
Output Select 3 and 2
These bits specify how the timer output level is to be
changed by a compare-match B of TCORB and
TCNT.
00: No change when compare-match B occurs
01: 0 is output when compare-match B occurs
10: 1 is output when compare-match B occurs
11: Output is inverted when compare-match B occurs
Output Select 1 and 0
These bits specify how the timer output level is to be
changed by a compare-match A of TCORA and
TCNT.
00: No change when compare-match A occurs
01: 0 is output when compare-match A occurs
10: 1 is output when compare-match A occurs
11: Output is inverted when compare-match A occurs
