Section 11 Timer W
Figure 11.8 shows an example of buffer operation when the GRA is set as an input-capture
register and GRC is set as the buffer register for GRA. TCNT operates as a free-running counter,
and FTIOA captures both rising and falling edge of the input signal. Due to the buffer operation,
the GRA value is transferred to GRC by input-capture A and the TCNT value is stored in GRA.
