6. Examples of Buffer Operation

Figure 14.38 shows an operation example in which GRA has been designated as an output

compare register, and buffer operation has been designated for GRA and GRC.

This is an example of TCNT operating as a periodic counter cleared by compare match B.

Pins FTIOA and FTIOB are set for toggle output by compare match A and B.

As buffer operation has been set, when compare match A occurs, the FTIOA pin performs

toggle outputs and the value in buffer register is simultaneously transferred to the general

The timing to transfer data is shown in figure 14.39.
