In the reset-synchronized PWM mode, three-phase output of positive and negative PWM
waveforms that share a common wave transition point can be obtained by combining channels 3
and 4.
When set for reset-synchronized PWM mode, the TIOC3B, TIOC3D, TIOC4A, TIOC4C,
TIOC4B, and TIOC4D pins function as PWM output pins and TCNT3 functions as an upcounter.
Table 11.37 shows the PWM output pins used. Table 11.38 shows the settings of the registers.
