Example of Cascaded Operation Setting Procedure: Figure 9.20 shows an example of the
setting procedure for cascaded operation.
Cascaded Operation Example (a): Figure 9.21 illustrates the operation when TCNT_2
overflow/underflow counting has been set for TCNT_1 and phase counting mode has been
designated for channel 2.
TCNT_1 is incremented by TCNT_2 overflow and decremented by TCNT_2 underflow.
