Cascaded Operation Example (d)

Figure 12.24 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.
