Section 10 16-Bit Integrated Timer Pulse Unit (ITU)
An example of buffer operation in complementary PWM mode between GRB3 and BRB3 is
shown in figure 10.52. By making GRB3 larger than GRA3 using buffer operation, a PWM
waveform with a duty cycle of 0% is generated. The transfer from BRB to GRB occurs upon
TCNT3 and GRA compare match and TCNT4 underflow.
