Figure 10.51 shows an example in which GRA is set to function as an input capture register
buffered by BRA, and TCNT is cleared by input capture B. The falling edge is selected as the
input capture edge at TIOCB. Both edges are selected as input capture edges at TIOCA. Because
of the buffer setting, when the TCNT value is captured into GRA at input capture A, the previous
GRA value is simultaneously transferred to BRA. Figure 10.52 shows the transfer timing.
