7.7 Sample Application
In the example below, the free-running timer channel is used to generate two square-wave outputs
with a 50% duty factor and arbitrary phase relationship. The programming is as follows:
(1) The CCLRA bit in the TCSR is set to 1.
Fig 7-15
(2) Each time a compare-match interrupt occurs, software inverts the corresponding output level
bit in the TCSR (OLVLA or OLVLB).
