Figure 12.3 Periodic Counter Operation
By setting a general register as an output compare register, compare match A, B, C, or D can
cause the output at the FTIOA, FTIOB, FTIOC, or FTIOD pin to output 0, output 1, or toggle.
Figure 12.4 shows an example of 0 and 1 output when TCNT operates as a free-running counter, 1
output is selected for compare match A, and 0 output is selected for compare match B. When
signal is already at the selected output level, the signal level does not change at compare match.
