PwmOutResetSync

In the reset-synchronized PWM mode, three-phase output of positive 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, TIOC4A, and TIOC4B pins function as PWM output pins and TCNT3 functions as an upcounter.
