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.
