(a)
Figure 12.16 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 12.4.5, PWM Modes.
