Buffer operation differs depending on whether GR has been designated for an input capture
register or an output compare register, or in reset synchronous PWM mode or complementary
PWM mode.
Table 13.8 shows the register combinations used in buffer operation.

When a compare match occurs, the value in the buffer register of the corresponding channel is
transferred to the general register.
This operation is illustrated in figure 13.35.
When an input capture occurs, the value in TCNT is transferred to the general register and the
value previously stored in the general register is transferred to the buffer register.
This operation is illustrated in figure 13.36.
