Figure 12.20 Buffer Operation Example (Output Compare Register)

Buffer Operation Examples—when TGR Is an Input Capture Register: Figure 12.21 shows

an example of TGRA set as an input capture register with the TGRA and TGRB registers set for

buffer operation.

The TCNT counter is cleared by a TGRA register input capture, and the TIOCA pin input capture

input edge is selected as both rising and falling edge. Because buffer mode is selected, an input

capture A causes the TCNT counter value to be stored in the TGRA register, and the value that

was stored in the TGRA up until that time is simultaneously transferred to the TGRC register.
