Section 10 16-Bit Integrated Timer Pulse Unit (ITU)
Figure 10.50 shows an example of input capture operation in buffer mode between GRA and BRA
with GRA as an input capture register. 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 BRA. The timing is shown in figure 10.51.
