3. Set bits CMD1 and CMD0 in TMDB to select complementary PWM mode. TIOCA3,
4. Reset TCNT4 (to H'0000). Set the non-overlap offset in TCNT3. Do not set TCNT3 and
5. GRA3 is the waveform period register. Set the upper limit of TCNT3–1 * . Set the transition
6. Set the PFC for the external pin to be used.
7. Set the STR3 and STR4 bits in TSTR to 1 to start the TCNT3 and TCNT4 counts.

compare match range of TCNT3 and TCNT4.
Note: * GRA3 = [cycle count/2] + [count of non-overlaps] - 2cyc=[upper limit of TCNT3]-1
Note: To re-establish complementary PWM mode after it has been aborted, start settings from
