Figure 10.23 illustrates the operation when TCNT_1 and TCNT_2 have been cascaded and the
I2AE and I1AE bits in TICCR have been set to 1 to include the TIOC2A and TIOC1A pins in the
TGRA_1 and TGRA_2 input capture conditions, respectively. In this example, the IOA0 to IOA3
bits in both TIOR_1 and TIOR_2 have selected both the rising and falling edges for the input
capture timing. Under these conditions, the ORed result of TIOC1A and TIOC2A input is used for
the TGRA_1 and TGRA_2 input capture conditions.

Figure 10.24 illustrates the operation when TCNT_1 and TCNT_2 have been cascaded and the
I2AE bit in TICCR has been set to 1 to include the TIOC2A pin in the TGRA_1 input capture
conditions. In this example, the IOA0 to IOA3 bits in TIOR_1 have selected TGRA_0 compare
match or input capture occurrence for the input capture timing while the IOA0 to IOA3 bits in
TIOR_2 have selected the TIOC2A rising edge for the input capture timing.
Under these conditions, as TIOR_1 has selected TGRA_0 compare match or input capture
occurrence for the input capture timing, the TIOC2A edge is not used for TGRA_1 input capture
condition although the I2AE bit in TICCR has been set to 1.
