Complementary PWM Mode
Channels 3 and 4 are paired for three-phase PWM output with non-overlapping complementary
waveforms. When complementary PWM mode is selected GRA3, GRB3, GRA4, and GRB4
automatically function as output compare registers, and TIOCA
TIOCB
counters.
Phase Counting Mode
The phase relationship between two clock signals input at TCLKA and TCLKB is detected and
TCNT2 counts up or down accordingly. When phase counting mode is selected TCLKA and
TCLKB become clock input pins and TCNT2 operates as an up/down-counter.

If the general register is an output compare register
When compare match occurs the buffer register value is transferred to the general register.
If the general register is an input capture register
When input capture occurs the TCNT value is transferred to the general register, and the
previous general register value is transferred to the buffer register.
Complementary PWM mode
The buffer register value is transferred to the general register when TCNT3 and TCNT4
change counting direction.
Reset-synchronized PWM mode
The buffer register value is transferred to the general register at GRA3 compare match.
