6. GRA3 is the waveform period register. Set the waveform period value in GRA3. Set the
transition times of the PWM output waveforms in GRB3, GRA4, and GRB4. Set times within
the compare match range of TCNT3.
X ≤ GRA3 (X: set value)
7. Set the PFC for the external pin to be used.
8. Set the STR3 bit in TSTR to 1 to start the TCNT3 count.
