5. Reset the TCNT3 (to H'0000). The TCNT4 need not be set.
6. The GRA3 is the waveform period register. Set the waveform period value in the GRA3. Set
7. Set the STR3 bits in the TSTR to 1 to let the TCNT3 start counting.
the transition times of the PWM output waveforms in the GRB3, GRA4, and GRB4. Set times
within the compare match range of the TCNT3.
