Examples of Buffer Operation

When TGR is an output compare register: Figure 10.19 shows an operation example in which

PWM mode 1 has been designated for channel 0, and buffer operation has been designated for

TGRA and TGRC. The settings used in this example are TCNT clearing by compare match B, 1

output at compare match A, and 0 output at compare match B.

As buffer operation has been set, when compare match A occurs the output changes and the value

in buffer register TGRC is simultaneously transferred to timer general register TGRA. This

operation is repeated each time compare match A occurs.

For details of PWM modes, see section 10.4.6, PWM Modes.
