Section 10 16-Bit Timer Pulse Unit (TPU)
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.
