• Manufacturer Part Number: HD64336901G
• Description: (HD64xxx Series) 16-BIT MICROCONTROLLER
• Manufacturer: Renesas Technology

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.
Figure 12.5 shows an example of toggle output when TCNT operates as a free-running counter,
and toggle output is selected for both compare match A and B.
