Section 10 Multi-Function Timer Pulse Unit 2 (MTU2)
(3)
Figure 10.22 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.

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