(2) Examples of Buffer Operation

(a) When TGR is an output compare register

Figure 10.15 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 on PWM modes, see section 10.4.5, PWM Modes.
