Section 11 Timer W
Figure 11.11 shows an example of buffer operation when the FTIOB pin is set to PWM mode and
GRD is set as the buffer register for GRB. TCNT is cleared by compare match A, and FTIOB
outputs 1 at compare match B and 0 at compare match A.
Due to the buffer operation, the FTIOB output level changes and the value of buffer register GRD
is transferred to GRB whenever compare match B occurs. This procedure is repeated every time
compare match B occurs.
Figures 11.12 and 11.13 show examples of the output of PWM waveforms with duty cycles of 0%
and 100%.
