Figure 10.50 shows an example of input capture operation in the buffer mode between GRA and
BRA with GRA as an input capture register. The 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. When the TCNT value is stored in GRA by input capture A, the previous GRA
value is transferred to the BRA. The timing is shown in figure 10.51.
