Figure 11.22 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 the TIOC1A rising

edge 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, the rising edge of both TIOC1A and TIOC2A is used for the TGRA_1

input capture condition. For the TGRA_2 input capture condition, the TIOC2A rising edge is used.

Figure 11.22 Cascaded Operation Example (b)

As I1AE in TICCR is 0, data is not captured in TGRA_2 at the TIOC1A input timing.
