Examples of Buffering: Figure 10.49 shows an example in which GRA is set to function as an
output compare register buffered by BRA, TCNT is set to operate as a periodic counter cleared by
GRB compare match, and TIOCA and TIOCB are set to toggle at compare match A and B.
Because of the buffer setting, when TIOCA toggles at compare match A, the BRA value is
simultaneously transferred to GRA. This operation is repeated each time compare match A occurs.
Figure 10.50 shows the transfer timing.
