Section 12 Multi-Function Timer Pulse Unit 2 (MTU2)
(4) Cascaded Operation Example (c)
Figure 12.23 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.
